In the 474th Brookhaven Lecture Oleg Gang discusses how Brookhaven scientists have devised a way of using strands of synthetic DNA attached to the surface of nanoparticles to instruct them to self-assemble into nanoscale structures, clusters, and three-dimensional organizations.
A novel multimodal optical nanoprobe is incorporated into a transmission electron microscope (TEM) sample holder. The nanoprobe allows scientists to perform all the usual experiments done in a TEM in addition to those involving optical excitation and measurement of the sample, electrical measurements on the sample, scanning tunneling microscopy (STM), and combinations of these measurements. Of particular utility is the ability to simultaneously measure optical and electrical properties of the sample at the nanoscale.
Building on the idea of using DNA to link up nanoparticles scientists at Brookhaven National Lab have designed a molecular assembly line for high-precision nano-construction. Nanofabrication is essential for exploiting the unique properties of nanoparticles in applications such as biological sensors and devices for converting sunlight to electricity.
Staff from Brookhaven's new Center for Functional Nanomaterials (CFN) describe how this advanced facility will focus on the development and understanding of nanoscale materials. The CFN provides state-of-the-art capabilities for the fabrication and study of nanoscale materials, with an emphasis on atomic-level tailoring to achieve desired properties and functions. The overarching scientific theme of the CFN is the development and understanding of nanoscale materials that address the Nation's challenges in energy security.
The Center for Functional Nanomaterials (CFN) at Brookhaven National Laboratory explores the unique properties of materials and processes at the nanoscale. The CFN is a user-oriented research center, with the double mission of being an open facility for the nanoscience research community and advancing the science of nanomaterials that address the nation's energy challenges.
One of ten national laboratories overseen and primarily funded by the Office of Science of the U.S. Department of Energy (DOE), Brookhaven National Laboratory conducts research in the physical, biomedical, and environmental sciences, as well as in energy technologies and national security. Brookhaven Lab also builds and operates major scientific facilities available to university, industry and government researchers. Brookhaven is operated and managed for DOE's Office of Science by Brookhaven Science Associates, a limited-liability company founded by the Research Foundation for the State University of New York on behalf of Stony Brook University, the largest academic user of Laboratory facilities, and Battelle, a nonprofit applied science and technology organization.
