Water-soluble Quantum Dots

Description

The water-soluble QDs are made by special surface modification, which have good biocompatibility, small nonspecific adsorption, high quantum yield, high molar extinction coefficient, stable optical properties, narrow emission spectrum. The QDs are easy to couple with biomolecules (antibody, protein, nucleic acid, etc.). and also is the best choice for the new generation of fluorescent labeled probe.
