Abstract

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The goal of this project is to test a new class of fluorescent biomarkers with strongly enhanced by metallic particles fluorescence response and develop a novel generic approach for ultra-sensitive fluorescence assay technology. The assay platform will utilize metal particles deposited on the glass/quartz surface covered with sub-nanometer layer of fluorescent biomarker. Fluorescence signal of such composite will be enormously enhanced (in many cases thousands fold). This will allow easy, quantitative and inexpensive fluorescence detection of minimal traces of specific antigens.
