Water-soluble QDs

InP/ZnS QDs  CdSe/ZnS QDs  CQDs


Mesolight water-soluble QDs for biomarkers are made by special surface modification of quantum dots. The products have the following excellent properties and are the first choice for bio-fluorescence marks.


Product advantages:

1.Special surface modification, good biocompatibility, small non-specific adsorption

2.High quantum yield and large molar extinction coefficient

3.Stable optical performance, narrow emission spectrum

4.Many types of products,large range of emission spectrum

5.Excitation multi-color display at the same wavelength, simultaneous detection of multiple indicators

6.With -COOH/-NH2 functional group, easy molecular coupling
