Abstract

The invention relates to a molecular imprinting photonic crystal for detecting glucose, which belongs to the technical field of applied chemistry and clinical analysis test. A method comprises the following steps: firstly, inserting a substrate subjected to hydrophilic treatment into PMMA colloidal pellet solution, and self-assembling pellets on the substrate to obtain a three-dimensional photonic crystal template; secondly, dripping molecular imprinting pre-polymerization solution on the edge of the three-dimensional photonic crystal template, and thermally polymerizing the template; and finally, cleaning the glucose imprinting template to obtain a glucose molecular imprinting photonic crystal template. The molecular imprinting photonic crystal has specific glucose adsorption performance, enables direct observation of the change, and fulfills the aim of real-time, quick and convenient detection.

Description

technical field [0001] The invention relates to a molecularly imprinted photonic crystal for glucose detection and an application thereof, which belongs to the technical field of applied chemistry and clinical analysis and testing. Background technique [0002] Molecularly imprinted polymers (MIPs) are polymerized by adding functional monomers and cross-linking agents in the presence of imprinted molecules (template molecules). After the polymerization reaction, the imprinted molecule is eluted to form a molecular recognition site complementary to the imprinted molecule in terms of functional groups and three-dimensional structure on the polymer skeleton. It has been confirmed that the specific recognition ability of MIPs to imprinted molecules is comparable to that of enzymes and antibodies. Photonic crystals (PCs) are nonlinear optical gels with continuous and regular pore structures. Photonic crystals with inverse opal structure can be obtained by template self-assembly...
