We investigated the optoelectronic properties of lead sulphide (PbS) quantum dot films in lithographically tailored gold nanogap electrodes. In particular, we aimed at the correlated measurement of photoconductivity and luminescence as a tool to characterize the charge dynamics from exciton generation to carrier extraction and recombination. Combining these measurements in an optical microscope with laser scanning excitation enabled, as well, the spatially resolved observation of the involved effects.

AbstractLuminescent CdSe-ZnS core-shell quantum dot (QD) bioconjugates were used as energy donors in fluorescent resonance energy transfer (FRET) binding assays. The QDs were coated with saturating amounts of genetically engineered maltose binding protein (MBP) using a noncovalent immobilization process, and Cy3 organic dyes covalently attached at a specific sequence to MBP were used as energy acceptor molecules. Energy transfer efficiency was measured as a function of the MBP-Cy3/QD molar ratio for two different donor fluorescence emissions (different QD core sizes). Apparent donor-acceptor distances were determined from these FRET studies, and the measured distances are consistent with QD-protein conjugate dimensions previously determined from structural studies.
