MANUFACTURING METHOD OF RANDOM COPOLYMER FOR SURFACE MODIFICATION OF QUANTUM DOTS AND METHOD FOR MODIFYING SURFACE OF QUANTUM DOTS USING THE SAME

摘要

TECHNICAL FIELD The present invention relates to a random copolymer for quantum dot surface modification, and a quantum dot using the same. More particularly, the present invention relates to a method for modifying a surface of a quantum dot, Random copolymers capable of surface modification of quantum dots, so that the quantum dots can be surface-modified. The random polymer according to the present invention can easily modify the surface of a quantum dot by merely mixing it with a quantum dot, and if a quantum dot is modified with a random polymer as the road, a random polymer can be formed in the existing quantum dot while maintaining the ligand, Since the surface of the quantum dot is exchanged with the ligand, the surface-modified quantum dot can have a compact size and the surface modification mechanism does not damage the surface of the quantum dot even though the surface modification mechanism is a ligand exchange reaction, The inherent optical properties can be maintained, and the biomolecular target molecules can be efficiently conjugated to each other and have excellent stability in water dispersion. Thus, the quantum dot surface-modified with the random polymer according to the present invention is applied to the bio-field, This is possible.
