aChange in CdTe fluorescence intensity at 535 nm during the binding time with different molar ratios of Au nanoparticle/CdTe nanocrystals in solution and b effect of gold nanoparticles concentration on the CdTe fluorescence quenching efficiency. Fluorescence intensity at 535 nm after complete binding [plateau region from figure (a)] was used in this plot. The gold nanoparticles used herein are protected with shortest spacer, tiopronin (methylene number = 0). The concentration of CdTe nanocrystal was 5.0×10-7 M in solution
