Custom Chiral Quantum Dot Enantiomer Recognition Services


Custom Chiral Quantum Dot Enantiomer Recognition Services

The customization of chiral quantum dots can bring you more comprehensive quantum dot products and services. Chiral quantum dots can recognize enantiomers, which is a very high speed. At present, we are promoting this project. Alfa Chemistry has a long history of innovation and introduction of advanced technology and talent to better serve customers in the future.


The fluorescence intensity of chiral quantum dots is obviously enhanced when isoleucine (L-Ile) exists, but the fluorescence intensity of chiral quantum dots does not change significantly when D-Ile exists. The quantum dot chiral sensing system has a fast response speed. The chiral quantum dot can identify the Ile enantiomer within 5 minutes, and the enantiomeric selectivity (IL/ID) can reach 2.2. L-Ile has a good linear relationship in the concentration range of 0 ~ 30 mM, and the LOD is 0.29 mM. The fluorescence intensity also increases linearly with the increase in the percentage of enantiomers of L-Ile in the mixture. Therefore, this method can not only realize the quantitative detection of L-Ile, but also determine the percentage of enantiomers in the racemate. Through molecular modeling, the chiral recognition mechanism can be explained by the difference in binding energy and interaction type between D-Ile and L-Ile and CCQDs. This method was applied to the detection of L-Ile in actual samples of functional beverages, and the detection results were consistent with the results of high performance liquid chromatography.
