CdTe quantum dots (QDs) were synthesized in aqueous solution using 2-mercaptoethylamine hydrochloride (CA) as stabilizing agents. The interaction between CA-CdTe QDs with human serum albumin (HSA) was investigated by ultraviolet–visible (UV–vis) absorption, circular dichroism (CD), fluorescence and resonance Rayleigh scattering (RRS) spectroscopy. CD spectra revealed that the conformation and microenvironment...
Thioglycolic acid (TGA) capped CdTe quantum dots (QDs) with the diameter of 2–3nm were synthesized. The interaction between CdTe QDs and chymotrypsin (chy) was investigated by ultraviolet–visible (UV–vis) absorption, fluorescence and resonance Rayleigh scattering (RRS) spectroscopy. Under pH 7.2, CdTe QDs effectively quenched the intrinsic fluorescence of chy via static quenching. The binding constants...
