Rapid and Efficient Detection and Identification of Pathogens and Proteins

Primary Inventors: 

This technology uses a novel, "chemical nose" approach to the detection and identification of pathogens and proteins. Classes of gold nanoparticle-fluorescent polymer complexes are developed as selective receptors-reporters for pathogen or protein binding. These receptor-reporter constructs function by selective binding to analytes through unique surface interactions between analytes and nanoparticles, producing distinct fluorescence response patterns upon the displacement of the bound fluorescent polymers. These response patterns are quantitatively differentiated by linear discriminant analysis.
