Abstract
A fluorescence assay for the sequential determination of lysozyme and trypsin was established based on l-cysteine capped CdTe quantum dots. Lysozyme with positive charges can interact with l-cysteine capped CdTe quantum dots. Lysozyme can be hydrolyzed into small fragments in the presence of trypsin, and the interaction between l-cysteine-capped CdTe QDs and lysozyme would be inhibited, which could be used for trypsin quantification.
