Cadmium sulfide is a chemical compound that is made up of inorganic elements. It is the major source of cadmium for all commercial uses since it is a simple to extract and purify chemical. Cadmium sulfide and cadmium selenide can combine to generate a solid solution, which is used to make a photoresistor that detects visible and near-infrared light.

Case 1: Surface coating of cadmium sulfide quantum dots
Quantum dots (QDs) are commonly used in a variety of applications, including electronics and medical. Alfa Chemistry can modify the surface of cadmium sulfide quantum dots (CdS-QDs) to support plant research.
Examples include studying the bioaccumulation and biological response of CdS-QDs compared to Cd2+ ions and bulk CdS through soybean seedlings. To learn more about how surface coatings affect quantum dot stability, uptake, translocation, subcellular localization, and cellular responses, we modified bare CdS-QDs with a variety of polar and surface-charged ligands. To prepare QD-TOPO, QD-PVP, QD-MAA, and QD-GLY, four common ligands were used: trioctylphosphine oxide, polyvinylpyrrolidone, thioglycolic acid, and glycine. acetic acid and glycine.
