DESCRIPTION:A novel sensing approach for the detection of analytes based o
 n the photonic properties of Quantum Dots (QD) will be described with part
 icular reference to medical applications. Photoluminescence (PL) from the 
 QD nanocrystal lattice is contained and stabilised by capping agents\, whi
 ch can be designed to react to microenvironmental molecules thus conferrin
 g 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 architectur
 es with tunnable emissions\n(480nm-410nm) offering multiplexing potential.
  The performance of a glucose sensing platform will be the model for the p
 roof-of-concept.\n
