▎ 摘　　要

NOVELTY - Molecularly imprinted polymer material comprises polypyrrole-modified graphene quantum dot with adrenaline as a template molecule which is having the structural formula of polypyrrole/graphene quantum dots-molecularly imprinted polymers (ppy/GQDs-MIPs). USE - The molecularly imprinted polymer material is useful for the detection of epinephrine (claimed). ADVANTAGE - The molecularly imprinted material: has high selectivity, strong sensitivity, low toxicity and good detection effect at the cellular level. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing a molecularly imprinted polymer material comprising (1) preparing a graphene quantum dot having uniform uniform particle size, and (2) adding the graphene quantum dots and adrenaline obtained during the polymerization of the pyrrole into a polypyrrole, stirring constantly, washing with acid for 3-5 times, removing the template molecule adrenaline, and then washing with water 3-5 times to obtain molecularly imprinted polymer nano-materials of polypyrrole-modified graphene quantum dots capable of adrenaline as a template molecule; (2) use of the molecularly imprinted polymeric material as probes for the detection of epinephrine; and (3) use method of molecularly imprinted polymeric material comprising adding polypyrrole/graphene quantum dots-molecularly imprinted polymers into the mother liquor containing epinephrine, and determining the fluorescence intensity of the system at the set excitation wavelength to obtain the mother liquor in epinephrine concentration according to fluorescence intensity.
