The water-soluble CdTe/CdSe/ZnS quantum dot products produced by Suzhou Beike Nano Co., Ltd. are core/shell/shell fluorescent nanomaterials with CdTe as the core, CdSe and ZnS as the shell, and the surface is wrapped by hydrophilic ligands. The quantum yield is 70%. It is especially pointed out that 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 sealed dark place at 4 degrees. It can be customized for customers. 620nm ~ Products with different grams at any wavelength of 820nm. This product has the characteristics of uniform particle size, broad absorption spectrum, symmetrical emission spectrum, high and stable fluorescence intensity.
At present, our company can provide four types of water-soluble CdTe/CdSe/ZnS quantum dots: (1) Carboxyl group with negative charge on the surface, 3-mercaptopropionic acid as the coating agent; (2) Carboxyl group with negative charge on the surface, polymer as the coating agent Coating agent; (3) The surface is a negatively charged carboxyl group, containing PEG chains, with excellent biocompatibility, and can be connected to antibody proteins with amino groups; (4) The surface is positively charged amino groups, containing PEG chains, biological phase It has excellent compatibility and can be connected to antibody proteins with carboxyl groups.

Warm tip: the products supplied by Beijing Beike Xincai Technology Co., Ltd. are only used for scientific research, not for human body
