Our objective is to develop a highly luminescent biomaterial system that can be conjugated to weakly fluorescing biological molecules for the development of biosensors. Semiconductor quantum dots (QDs) have the potential to become a new class of fluorescent bioprobes for many biological applications. Among biomolecules, DNA has a fundamental role in biological processes. The combination of molecular biology (for engineering DNA with the desired functional and/or self-assembling properties) and nanophotonic technology (for device fabrication) thus becomes the tool to realize a new class of nanophotonic elements.
