Abstract

The invention provides a photonic crystal hydrogel film, which comprises Fe3O4 nano particles and polyacrylamide-methylene bisacrylamide-N,N'-bis(acroloyl)cystamine hydrogel. The invention further provides a preparation method. Fe3O4 nano particles, acrylamide, methylene bisacrylamide, N,N'-bis(acroloyl)cystamine, and a photoinitiator are evenly dispersed into an organic solvent, then a magnetic field is loaded, and finally the solution is irradiated by UV rays to obtain the photonic crystal hydrogel film, which can be applied to naked eye detection or a bio-molecular sensor. By loading a magnetic field, Fe3O4 nano particles are arranged in a one-dimensional chain; then the film is synthesized through UV irradiation; the film has a single color, is pure, can respond to reductive glutathione, has high specificity and sensitivity on reductive glutathione, can be applied to naked eye detection, and solves the problems that the detection of reductive glutathione is very expensive and the operation is tedious; and a novel method is provided for the detection of reductive glutathione in a water solution.

Description

technical field [0001] The invention belongs to the technical field of photonic crystals, and in particular relates to a photonic crystal hydrogel film and a preparation method and application thereof. Background technique [0002] With the increasing number of people with disease worldwide and the increasing number of deaths from advanced disease, highly sensitive detection of early disease has received increasing attention. Biomolecules in the human body play an important role in the life activities of the human body and are of great significance in the early diagnosis of diseases. Reduced glutathione is a ubiquitous thiol polypeptide in cells, which plays an essential role in maintaining redox balance in the body, eliminating free radicals in the body and cell proliferation. Due to the antioxidant effect of reduced glutathione, the detection of reduced glutathione has important applications in the pathological research of some diseases, such as cancer, Alzheimer's diseas...
