October, 2005: Kevin D. Belfield (PI) and Andres D. Campiglia (co-PI) received the Type H award from The Petroleum Research Fund of the American Chemical Society. The endowment includes $31,080 for "Optical, Photonic, and Electronic Materials ACS-PRF Summer School." The objective of the ACS PRF Summer School on Optical, Photonic, and Electronic Materials, to be held at UCF in June 2006, is to bring aspiring chemists at relatively early stages of their careers, along with faculty from two-year colleges, for an intensive educational experience in cutting edge materials that are used in a number of emerging technologies.

January, 2005: Mike Sigman and his co-investigators, Andrew Campiglia and Kevin Belfield, received a contract for a grant from DARPA.

Research
Our research focuses on the development of novel analytical approaches based on multidimensional luminescence spectroscopy. We take advantage of fluorescence and phosphorescence phenomena to directly determine target compounds in complex samples, to study mechanisms of interaction between chemical species in the liquid phase, and to elucidate solid-liquid interfacial phenomena. Our efforts directly impact areas of chemical sensing, environmental chemistry, liquid chromatography and capillary electrophoresis, and biological, forensic and pharmaceutical analysis. Current efforts are divided in four projects. First, we are developing new experimental methodologies and instruments for absorption, excitation, and multidimensional luminescence analysis at liquid nitrogen (77°K) and liquid helium (4.2° K) temperatures. This approach is based on the use of cryogenic fiber optic probes, making it possible to perform low-temperature measurements in a matter of seconds. We have developed the only existing method that provides unambiguous determination of dibenzo[a, l]pyrene in contaminated samples. This compound is the most carcinogenic polycyclic aromatic hydrocarbon known. Our second project deals with new strategies for targeting specific proteins in complex physiological fluids. Protein recognition is achieved via luminescence probes consisting of lanthanide ions incorporated into polymerized liposomes. The two remaining projects target specific needs in forensic science and nanotechnology. The forensic science project investigates ways to identify textile fibers encountered as physical evidence in criminal investigations. The nanotechnology project focuses on the development of new separation methodology with potential impact on biotechnical, biochemical, and biological research.

Purifying mercury-polluted water Using tiny pieces of gold and the properties of light, scientists can now quickly and inexpensively detect even trace amounts of the pollutant. In the near future, this process can be used to create water filters and reclaim contaminated water.
