Quantum Dot Biosensors- Christian Cimorra (TFM)

A novel sensing approach for the detection of analytes based on the photonic properties of Quantum Dots (QD) will be described with particular reference to medical applications. Photoluminescence (PL) from the QD nanocrystal lattice is contained and stabilised by capping agents, which can be designed to react to microenvironmental molecules thus conferring a quantifiable photo-physical effect. The functional agent of choice is the biomolecule Glutathione (GSH) due to its reducing potential and metal-ion complexation abilities. In addition, the relatively simple and facile synthesis methodology delivers controllable size-dependant QD architectures with tunnable emissions (480nm-410nm) offering multiplexing potential. The performance of a glucose sensing platform will be the model for the proof-of-concept.
