About
Technology This platform technology employs a new class of nanoscale fluorescent biosensors with rapid and quantifiable responses to the binding of target bioanalytes. Each biosensor consists of a semiconductor nanocrystal (quantum dot) tethered to a biomolecular probe via a stabilizing linker. The binding of the biomolecular probe to its intended target bioanalyte causes a change in the fluorescence emission intensity of the quantum dot, enabling instantaneous sensing of the presence of the bioanalyte. Quantitative analysis of the bioanalyte can be readily performed by using simple dose-response assays. Applications • Point-of-care medical diagnostics • High-throughput screening of biomolecules for drug discovery and development • Rapid testing of biological threats for public safety and military applications
