Some of the more shadowy secrets of biology may soon be illuminated through the use of a new type of fluorescent probe developed by scientists at Berkeley Lab.
A joint LBNL-UC Berkeley research team led by Paul Alivisatos and Shimon Weiss has announced the development of nanometer-sized crystals of semiconductors, such as cadmium selenide and cadmium sulfide, that can be used as fluorescent probes for the study of biological materials. These semiconductor nanocrystals offer a distinct advantage over conventional dye-molecules in that they emit multiple colors of light, which means they can be used to label and measure several biological markers simultaneously.
The unique optical properties of these semiconductor nanocrystals also hint at the possibility of observing changes that take place in labeled biological systems, such as living cells, over a period of time. This research was reported in the Sept. 25 issue of Science.
Alivisatos is a leader in the production by chemical means of semiconductor nanocrystals, simple inorganic solids consisting of a hundred to a hundred thousand atoms. He holds a joint appointment as a senior staff scientist with the Materials Sciences Division (MSD) and as a professor of chemistry at UC Berkeley. Weiss, a staff scientist with MSD, is an authority on single molecule fluorescence and spectroscopy. He approached Alivisatos with the proposal for this joint study.
Other members of the team who co-authored the paper in Science were Marcel Bruchez Jr., who also holds a joint LBNL-UCB appointment, and Mario Moronne and Peter Gin, with the Life Sciences Division.
"Form follows function" is the golden rule in cell biology, which is why microscopy has been the heart and soul of this research field and fluorescent-labeling, one of its most widely used tools. In fluorescent labeling, markers, usually antibodies that attach themselves to specific proteins, are tagged with dye-molecules that fluoresce, or emit a specific color of light when stimulated by laser light, usually from a confocal microscope.
"Sometimes, in order to fully characterize a sample, a population of cells for example, you need to look at combinations of markers," says Alivisatos. Such measurements require multiple-color light emissions which are difficult to obtain with conventional dye molecules.
"Ideal probes for multi-color experiments should emit at spectrally resolvable energies, should have a narrow, symmetric emission spectrum, and the whole family should be excitable at a single wavelength," the authors of the Science paper wrote.
Semiconductor nanocrystals met these demands in a "dual emission from single excitation" labeling experiment on mouse tissue cells called 3T3 fibroblasts. A core nanocrystal of cadmium selenide was enclosed within a shell of cadmium sulfide to boost the amount of fluorescence and reduce photochemical degradation. This core-shell combo was then enclosed within a shell of silica for water solubility and biocompatibility.
With earlier work by Alivisatos having shown that the color of light emitted by a semiconductor nanocrystal depends upon its size, the mouse cells were labeled with two different sizes of core-shell nanocrystals. It was also known that modifying the surface of the silica shell can be used to selectively control its attachment to components within a cell. In this case, the smaller nanocrystals (two nanometers), which fluoresced green, were modified to penetrate the nucleus of each cell, and the larger nanocrystals (four nanometers), which emitted red light, were modified so that they would attach themselves to actin filaments along the outer cell membrane.
Using wide-field microscopy, the green and red labels were clearly visible to the naked eye and could be photographed in true color with an ordinary camera. Confocal microscopy images showed that cell nuclei had been penetrated with the green probes and the actin fibers had been stained red. After repeated scans, the nanocrystal labels showed far less photobleaching than would occurred in the control sample labeled with conventional dye molecules.
"The development of semiconductor nanocrystals for biological labeling gives biologists an entire new class of fluorescent probes for which no small organic molecule equivalent exists," the authors of the Science paper wrote. "These nanocrystal probes can be complementary and in some cases may be superior to existing fluorophores."
The authors also assert that, compared with conventional fluorophores, semiconductor nanocrystals have a "narrow, tunable, symmetric emission spectrum, and are photochemically stable." These features, along with a relatively long fluorescence lifetime (hundreds of nanoseconds), indicate that in addition to serving as direct probes, semiconductor nanocrystals could also be used as "sensitizers" for traditional dye-molecule probes, meaning they transfer their excitation energy to the dye-molecule.
An earlier research team led by Weiss demonstrated that this energy sensitizing phenomenon, known as fluorescence resonance energy transfer (FRET), when it takes place between a single donor and a single receptor, could allow for the labeling and observation of dynamic events such as conformational changes in a protein.
"The use of semiconductor nanocrystals should allow us to do unique FRET experiments," says Weiss. "For example, labeled molecules could be made to emit different colors at different times of an event."
Weiss and Alivisatos and their co-authors also believe that semiconductor nanocrystals could be applied to x-ray- and electron-based imaging techniques, and could serve as tunable infrared dyes for detecting fluorescence in, among other things, blood samples.

Four of the five candidates for Mayor of Berkeley in this November's election will participate in a brown bag forum at noon on Wednesday, Oct. 14, in the Bldg. 50 auditorium.
The event was scheduled because of the increasing attention the city has paid to the operations of Berkeley Lab. According to the Lab's economic impact analysis, more than 1,000 of the Laboratory's employees live in Berkeley.
The candidates--incumbent Shirley Dean, Michael Delacour, Don Jelinek, and Robert Krumme, will each be given seven minutes to make a statement, and then will take questions from the audience. The event will be moderated by Reid Edwards, Berkeley Lab's manager of government relations. All Laboratory employees are encouraged to attend.

It was not so long ago that representatives from the Department of Energy would come to the Laboratory once a year on safety checks, bringing along a fat checklist. Say, for example, the fire engineer inspected the Firehouse. What he would look for was the number of sprinklers, the placement of fire doors, the number of people in the department. Three guys on the engine--check. Fire door here missing--no check. That's how Dick Nolan, DOE's Berkeley site manager, remembers the old way of going about EH&S business, one that resulted into what he calls a "checklist mentality."
Not anymore. What the DOE and the Laboratory focus on now is results. Instead of dictating a safety protocol to the Lab, the DOE makes sure the performance is up to par year-round. In the case of the Fire Department, that means assessing actual response time in an emergency situation. "It's things that make sense," Nolan says. "We shifted from a compliance mentality to what we call operational awareness. And instead of coming once a year to do it, we're engaged with the Laboratory the whole year. The Laboratory has opened up to us."
Over the last few years, representatives of Berkeley Lab and the DOE have worked closely together to develop the Laboratory's recently-implemented Integrated Safety Management (ISM) Plan, which reflects an entirely new approach to safety in the workplace. Instead of safety being seen as a separate function, distinct from all other activities at the Laboratory, the new plan seeks to incorporate safety into the larger picture. And for all its daunting title, the Integrated Safety Management Plan is actually based on a very simple, common sense principle: integrate safety awareness and planning into day-to-day business.
"Integrated safety management starts from a philosophy of looking at the work that we're doing," says David McGraw, head of the Lab's Environment, Health and Safety Division. "As we design the work, we design right into it the EH&S requirements. We want to build a habit for the individual investigators to think in a different way about safety: to think about it the way they think about their work and their research. This approach allows us to tailor the requirements to the work being done."
The concept may sound very simple, but it took the DOE a long time to reject the traditional, one-size-fits-all approach to EH&S. The change, Nolan says, was brought about both by a shift in industry practices and by a new direction from Washington, as demonstrated in Vice President Gore's Government Performance and Results Act.
"That has encouraged a revolution in government focusing on results," Nolan said. "In many respects that philosophy is reflected in ISM. Instead of safety being a stand-alone function that somebody else does, that EH&S does, it is something that you're responsible for."
In practical terms, ISM means that safety considerations are to be included in project planning just like all other elements, such as budget considerations or choice of equipment. Says McGraw: "My goal is to get to a place in EH&S where you don't think about it. Safety awareness becomes second nature."
ISM is based on seven guiding principles that provide a framework for the plan, guide its implementation and provide test points for evaluating its effectiveness. Central to these are "line management responsibility" and "clear roles and responsibilities."
"In final analysis," Nolan says, "somebody should be fired if there are serious safety deficiencies that are not getting corrected. And the person getting fired should be clearly identified."
Other principles include competence commensurate with responsibility, balanced priorities, identification of EH&S standards and requirements, hazard controls tailored to work being performed, and operations authorizations.
On one hand, this approach seeks to decentralize responsibility for safety in the workplace, with the divisions taking on an increasingly greater share of it. At the same time, McGraw says, EH&S staff will go out in the field more, particularly in the initial stages of implementation, to spend time partnering with researchers and providing them with the resources and expertise to help them build safety into their day-to-day work.
"I hope this will improve the respect that researchers have for EH&S professionals, and vice versa," he said.
This mutual respect was evident from the start of the process, Nolan says. As the ISM Plan was being developed last fall, the DOE team and Lab managers worked together on division safety plans. "That shows a high degree of trust between the Laboratory and DOE," he said. "It's unprecedented, to my knowledge, for a Laboratory to open up its internal processes by inviting the DOE to review division plans."
McGraw concurs, praising the way division directors have stepped up to the challenge and been personally involved in the development of the plans. "The response was much better than I could have hoped for," he said. "Not only has each division director written a customized division safety plan, but defended it in front of management."
Just because the new plan is in place, however, does not mean that the bulk of the work is done. In fact, both Nolan and McGraw caution, the real challenges still lie ahead: adjusting to the new way of doing business and establishing measurements to ensure the plan is being effectively implemented. "People are going to have to change their way of thinking," McGraw says. "And that's very hard for people to do. It's the most difficult single impediment I see."
For now the logistics are in place. The plan has been endorsed at the highest levels of management, both at the Laboratory and at the DOE. It has been embraced at the division level and is now filtering down into operations. And EH&S professionals continue to provide operational divisions with the expertise needed to comply with the new vision. What's left is for the plan to stand the test of time and turn this overarching vision into reality.
"Development of this program has given the Laboratory as well as our local operations office a lot of visibility," says Nolan. "It is looked upon as a model. I'm proud of that, and the Laboratory should be very proud. Now we just need to carry through and make sure it works. We're off to a good start. We're on our way."
It takes only five minutes to complete, but it will help us publish a better paper. How else can we know what you like and what you don't? Please complete the Currents Readership Survey on Page 3 and return it to us by Oct. 16. Thank you.
Energy Research Office Renamed, Gets Funding Boost
Under the energy and water appropriations bill approved by Congress last week, DOE's Office of Energy Research will be renamed the Office of Science and will receive a 16 percent boost in funding in FY99. Martha Krebs, director of the office, says that the extra funding shows Congress understands the value of research activities at DOE.
The bill provides $2.6 billion in FY99 for science programs at DOE, compared to the Administration's request of nearly $2.5 billion and the $2.2 billion approved in FY98. President Clinton must sign the bill to make it official.
A major beneficiary of the additional funding is the Spallation Neutron Source (SNS), the world's largest neutron-scattering device, scheduled for completion in 2005 at Oak Ridge National Laboratory. House and Senate conferees agreed to provide $130 million for SNS. While that is $40 million below DOE's request, it is $30 million above the level the House version of the bill would have provided.
Krebs believes the $40 million difference can be recouped in later years, and said that Congressional approval of a significant amount of funding for SNS, DOE's single biggest project for the foreseeable future, shows appreciation for the value of large-scale research.
"We're back in the business of building big facilities," Krebs says.

Harvard University finished first in the latest ranking of U.S. research universities, according to the Institute for Scientific Information in its latest issue of ScienceWatch. Harvard not only churned out more papers than any other university between 1993 and 1997, but the work was rated as having higher scientific impact across the board. Stanford finished second and UC Berkeley seventh.
To rank the top 100 federally funded research universities in 21 separate fields, ScienceWatch worked out the average number of times that papers from researchers at each institution were cited in another paper. These scores were then calculated as a percentage above or below the world average for papers in the same field, to yield an estimate of their "relative impact."
Harvard placed in the top 10 in 17 of the 21 categories, ScienceWatch reports. It was followed by Stanford, (13 top-10 placings), Caltech (11), Yale (9), University of Michigan (9), MIT (8), UC Berkeley (7), University of Washington (6), UC Santa Barbara (6), Cornell (6), and UC San Diego (6).

Berkeley Lab Director Charles V. Shank has testified before Congress that the U.S. Department of Energy and its federal laboratories have made significant progress in improving efficiencies and unlocking bureaucratic logjams since 1995.
In comments presented on Sept. 23 to the Subcommittees on Basic Research and Energy and Environment of the House Science Committee, Shank cited an atmosphere of trust and a commitment to partnerships as prime reasons why operations have been more effective and efficient. He was among several witnesses addressing reforms that have been implemented within the DOE since the so-called "Galvin Report" criticized various aspects of the department's management three years ago.
Using Berkeley Lab's experience as a model, Shank reviewed several examples of improved productivity through the elimination of costly administrative systems, unnecessary prescriptive oversight, and diffusion of responsibility.
"The growing level of trust and mutual respect between [the DOE and the laboratories] has resulted in very positive results that have saved the nation's taxpayers many millions of dollars," he told the panel. At Berkeley alone, he noted, "the combined effort in streamlining, outsourcing, and administrative systems updating resulted in a reduction in our composite overhead rate of 17 percent."
Shank cited assistance received from DOE's Oakland site office that allowed Berkeley Lab to gain access to low-cost federal power from the Western Area Power Administration, saving $2.85 million since 1995. A streamlined procurement system resulted in $500,000 savings in fiscal 1998 alone.
Shank said the new working relationships have also improved operating activities, leading to the implementation of the Integrated Safety Management and Work Smart Standards programs, the Nuclear Regulatory Commission pilot on external regulation, and more effective contract management. Efficiencies achieved in the National Environmental Policy Act "significantly reduced the number of steps and amount of paperwork passed from office to office." Streamlined support services, through outsourcing and systems updating, allowed an 18 percent reduction in personnel supporting the overhead budget, increasing the ratio of scientific staff to support staff at Berkeley, he added.
At the same time, "we have also increased our investment in infrastructure improvements," resulting in "a 50 percent reduction in the annual backlog of plant maintenance work, and a corresponding reduction in demands for future infrastructure projects," Shank said in his testimony.
He pointed out several examples of the DOE's more effective use of its national laboratories through partnerships and primary competencies: the Joint Genome Institute, combining the talents of Berkeley, Livermore and Los Alamos scientists; the Spallation Neutron Source, to be located at Oak Ridge; and the B-Factory project at the Stanford Linear Accelerator Center.
"In each of these projects," Shank said, "DOE is taking advantage of the unique strengths and capabilities of each institution. This is a far more efficient process than building up new teams at each site for each new project."
Shank concluded by saying, "We are working in greater partnership among the laboratories and with the DOE to insure that our laboratories remain focused on their missions, maintain their core competencies and infrastructure, and conduct their business in a cost effective manner."
Congresswoman Barbara Lee (D-Oakland), a member of the House Science Committee who welcomed Shank to the hearing, acknowledged in a prepared statement that "Berkeley Lab has incorporated many aspects of reform in its current operations and has developed a mutual relationship with the DOE located in Oakland to pursue substantive measures to ensure effective and efficient management.
"One of the things that has been encouraging," she said, "is the Lab's effort to reach into the community to utilize local people, business and agencies with which to contract to implement some of the functions of the Lab."--Ron Kolb

Lab Director Charles Shank has announced the selection of 73 projects for support by the Laboratory Directed Research and Development (LDRD) Program for Fiscal Year 1999.
A total of about $9.2 million in both operating expenses and capital equipment has been allocated for LDRD. One hundred seventy-one proposals were submitted requesting a total of $27.1 million in response to the Call for Proposals issued earlier this year (see Currents, March 6, 1998). The proposals were evaluated in a review process that used the scientific judgment and priorities of the division reviews and the director's review committees.
"The LDRD program is a primary mechanism to support new ideas as well as strengthen Berkeley Lab in important stra-tegic directions," Shank said.
"This year we had an abundance of riches to choose from, with the result that this was also one of our most competitive years. Among the projects funded, key strategic directions included computational proposals, research and development at the Advanced Light Source, and in the physical biosciences area."
Proposals funded included cross-divisional, multi-investigator, and individual investigator projects. Director Shank expressed his appreciation to all principal investigators who submitted proposals for their effort and creativity.
This November the Laboratory is reviving its annual charity giving campaign with a revised version called Berkeley Lab SHARES (Science, Health, Academics, Resources, Education and Services). Lab employees will receive their information packets by the end of October and will be able to choose the charity of their choice.
"As one of the world's premier scientific research organizations, the Laboratory has an outstanding record of contributing to the betterment and understanding of our world," said Laboratory Director Charles Shank. "Berkeley Lab SHARES gives you the opportunity to contribute as an individual to any of hundreds of non-profit organizations, which also seek to enhance all of our lives, whether by helping our communities, protecting natural resources, or supporting health-related research."
Berkeley Lab SHARES will allow employees to pick from literally hundreds of non-profit organizations represented by three umbrella organizations: United Way Bay Area, EarthFirst of California, and Combined Health Appeal. Organizers of the campaign have also chosen to include 19 Bay Area organizations which have links to the Laboratory and its mission.
Employees who wish to participate should return their forms in the preaddressed envelope by Friday, Nov. 20. Donations can be made either by enclosing a check or opting for payroll deductions, which woud take effect starting in January 1999.
Over the next few weeks, Currents and Headlines will feature more information about the campaign, the participating organizations and those who ultimately benefit from them. On Wednesday, Oct. 28, a fair will be held from 11:30 to 1:30 in or outside the cafeteria, offering additional information about the United Way, Combined Health Appeal and EarthFirst California organizations and their member agencies. Also attending will be several East Bay organizations supported by the Lab's campaign.
More information about the SHARES campaign will soon be available on the web at http://www.lbl.gov/shares/.
