Overview

Description

Carboxyl quantum dots can be obtained by surface modification of oil-soluble quantum dots with polymers. They can be uniformly dispersed in aqueous solution (such as borate buffer, PBS buffer solution, etc.), and the surface carboxyl groups are reactive. By coupling biomolecules (proteins, antibodies, nucleic acids, etc.), carboxyl quantum dots can be used as a new type of fluorescent probe in the field of biomedical detection.
