Dr. Waggoner's research has focused on development of fluorescence-based detection systems for biology and biotechnology. The cyanine dye fluorescent labeling reagents developed in the laboratory have become widely used in industry and academic research for multicolor analysis of proteins, nucleic acids, cells and tissues with imaging microscopes and flow cytometers. Dr. Waggoner is currently leading the Molecular Biosensor and Imaging Center into development of microbiosensors for studying protein regulatory processes in living cells and tissues. The Center also has a NASA project for detecting sparse microorganisms in extreme environments.
In the new optical biosensor initiative, the Waggoner group and its collaborators is creating a fundamental sensor unit technology for a new and very broad class of biosensors. We envision this technology will provide a very powerful, and almost generic, tool for detecting a very wide range of important biological regulatory molecules, "target molecules", in cells and in the interstitial spaces between cells. The sensors are intended to sensitively and rapidly detect many targets simultaneously in a tissue.
The sensor units are generated by combining genetically engineered, target-binding proteins and environmentally sensitive fluorescent dyes that report target binding. The sensor units will be incorporated into intracellular sensors, sensor particles and optical fiber sensors for interstitial spaces in tissues, sensors on chips for in vitro assays, and sensors for high throughput automated homogeneous assays in pharmaceutical drug discovery.
