▎ 摘　　要

NOVELTY - Preparing graphene oxide quantum dots (GOQDs) loaded polydiacetylenes (PDA)-ir-molecularly imprinted polymer (MIP) molecularly imprinted fluorescence sensor comprises using dopamine as functional monomer and antibiotic molecules as template molecules, self-polymerizing on the surface of carboxy graphene oxide quantum dots under the alkaline environment, obtaining GOQDs loaded PDA-MIP, concentrating, and eluting to obtain GOQDs loaded PDA-ir-MIP molecularly imprinted fluorescent sensor. USE - The GOQDs loaded PDA-ir-MIP molecularly imprinted fluorescent sensor is useful for selective fluorescence detection of antibiotic substance (claimed). ADVANTAGE - The sensor combines good optical properties of carboxy graphene oxide quantum dots and specific recognition ability of molecularly imprinted polymers, allows molecularly imprinted polymer shell to provide protective layer for the quantum dots, makes physical and chemical properties more stable, has simple preparation process, fast detection speed, does not require sample pre-processing, is environmentally friendly, has low cost advantages, and exhibits wide application prospect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for GOQDs loaded PDA-ir-MIP molecularly imprinted fluorescent sensor.
