Who knew that Dr. R. Bruce Weisman, Rice professor of Chemistry, would become an entrepreneur and found a technology company, Applied NanoFluorescence? In 2007, The Houston Business Journal awarded the Paul Frison Accelerator Award to the new company, which experienced more than 75 percent growth in revenue between 2005 and 2006.
"I am most proud of the capabilities of the instruments that we build and of the fact that they are finding good use in leading laboratories around the world," said Weisman on the success of his company.
Weisman’s current research at Rice involves basic and applied studies of carbon nanotubes using near-infrared fluorescence. He and his research group investigate the spectroscopy and photophysics of fullerenes and carbon nanotubes. All of these are closed nanoscopic structures formed from carbon atoms. Fullerenes, such as C60, C70, and their chemical derivatives, have unusual molecular properties that cause interesting behaviors following the absorption of light. Time-resolved absorption and emission methods are used to study radiationless decay, photochemical reactions, and energy transfer in fullerenes. Following the discovery in Weisman’s lab of near-infrared nanotube fluorescence, the group has measured and unraveled the absorption and emission spectra of more than 30 semiconducting nanotube species. Follow-up projects include detailed elucidation of nanotube electronic structure, as well as applications in non-invasive biomedical imaging and analytical nanotechnology.
Dr. Weisman earned his bachelor’s degree from the Johns Hopkins University and his doctoral degree from the University of Chicago. The opportunity to do research and teaching “in a high quality environment” is why he chose Rice.
One of Weisman’s favorite things about Houston is the mild winter weather, which is understandable since his home town is Baltimore, Maryland. The multicultural aspect of the nation’s fourth largest city is another favorite element of Houston, where he and his wife, a Rice Biochemistry & Cell Biology Professor, live with their daughter.
