Protein-Conjugated Quantum Dots for Detecting Trypsin and Trypsin Inhibitor Through Fluorescence Resonance Energy Transfer


We have developed quantum dot probes for detecting trypsin (Try) and trypsin inhibitor (TI) in aqueous solutions through fluorescence resonance energy transfer (FRET). Green-fluorescent CdTe quantum dots (QDs) served as the energy donors and rhodamine isothiocyanate (RITC) conjugated to bovine serum albumin (BSA-RITC) was the acceptor. By simply mixing the… (More)
