Abstract
The invention discloses a water-soluble quantum dot and a preparation method thereof. The method comprises the following steps: adding modified unsaturated carboxylic acid polymer into an oil-solublequantum dot solution to perform ligand exchange, and centrifuging to obtain the water-soluble quantum dot containing modified unsaturated carboxylic polymer ligand on surface, wherein the modified unsaturated carboxylic polymer is unsaturated carboxylic polymer modified by end-site-sulfydryl-substituted organic primary amine which is a polydentate ligand, and sulfydryls therein can provide stronger coordination ability for the surface of the quantum dot, so that stability and high light intensity of the quantum dot can be greatly improved; and carboxyl on the surface of the unsaturated carboxylic polymer can provide stronger water solubility and biofunctionability for the quantum dot.
