摘要：
Hybrids of biomolecules and semiconductor quantum dots (QDs) are functional units for the optical, photoelectrochemical, and electrochemical analysis of biorecognition events or biocatalyzed transformations. The size-controlled fluorescence properties of QDs enable multiplexed bioanalysis, and by their coupling to appropriate quencher units, the optical probing of dynamic biocatalytic processes is feasible. The integration of electrodes into biomolecule-QD hybrids allows the measurement of biorecognition processes or transformations by photocurrents. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
