The water-soluble CdTe/CdSe/ZnS quantum dot products produced by Suzhou Beike Nano Technology Co., Ltd. are based on CdTe as the core, CdSe and ZnS as the shell, and the surface is a core/shell/shell fluorescent nanomaterial wrapped by a hydrophilic ligand. The average quantum yield is 70%. In particular, this product still has a quantum yield of more than 40% in the near-infrared band. It should be stored away from direct sunlight and stored in a 4 degree sealed dark place. It can be customized for customers to produce 620nm Products with different grams of any wavelength at ~820nm. This product has the characteristics of uniform particle size, broad absorption spectrum, symmetrical emission spectrum, high and stable fluorescence intensity.

The company currently provides four types of water-soluble CdTe/CdSe/ZnS quantum dots: (1) negatively charged carboxyl groups on the surface, 3-mercaptopropionic acid as a coating agent; (2) negatively charged carboxyl groups on the surface, and polymers as Coating agent; (3) The surface is negatively charged carboxyl group, containing PEG chain, which has excellent biocompatibility and can be connected to antibody proteins with amino groups; (4) The surface is positively charged amino group, containing PEG chain, biological phase It has excellent capacity and can be connected to antibody proteins with carboxyl groups.

Products with PEG chains are not available for trial
