Perovskite Quantum Dots Based on Cholesterol Fluorescence Detection Services

Perovskite quantum dots can be used as fluorescent probes to detect cholesterol. Our professional team can bring customers the most comprehensive services, we have many years of synthetic quantum dot history and a series of quantum dot services, you can feel at ease to tell us your needs, we will bring you the most suitable solution.


Cholesterol (CHO) is an indispensable biomolecule in human and animal tissue cells. However, a large number of medical investigations and studies have shown that high CHO content in the human body can easily cause cardiovascular diseases such as arteriosclerosis. Among the current common methods for detecting CHO, chromatography can realize the determination of cholesterol in complex systems, but requires pre-processing of samples. The equipment is large in size and expensive, which cannot meet the needs of rapid detection. Colorimetric and electrochemical methods are relatively simple, but need to use cholesterol oxidase to improve its selectivity, and the repeatability and stability of the method are limited by enzyme activity. The fluorescence method has simple operation process, fast response, accurate and sensitive results, and is a good choice for cholesterol determination.


As a supplier of quantum dots, we also provide a series of services related to quantum dots. Our research team comes from all directions. Our services are not limited to providing products. We can also provide corresponding solutions for the applications of quantum dots, including optical components and medical testing. The following is our quantum dot service, we are always working hard to explore new solutions.

Alfa Chemistry adheres to a serious and responsible attitude towards customers, providing customers with product solutions as well as testing and data analysis services.

Detection process

CsPbBr3 QDs is used as the signal unit, tetramethoxysilane (MTMOS) is the crosslinking agent, and 3-aminopropyltriethoxysilane (APTES) is the functional monomer. It interacts with the template molecule CHO through van der Waals forces and hydrogen bonds. The sol-gel process introduces CHO into the SiO2 network structure. After removing the template molecules, a site that can selectively recognize CHO is formed; at the same time, CsPbBr3 QDs are encapsulated in the formed silicon layer network structure, which improves the performance of CsPbBr3 QDs. Stability, a fluorescent sensor platform (MIPs/CsPbBr3@Si O2QDs) with specific recognition ability for the template molecule CHO is obtained.
