CdSe Quantum Dots Enhance Electrical and Electrochemical Signals of Nanogap Devices for Bioanalysis

CdSe quantum dot-labeled streptavidin (CdSe QD–SAv) is introduced into nanogap to amplify the current and impedimetric signals generated in a biosensor for detecting the biotin–streptavidin binding event by electrical and electrochemical measurements.
