The invention provides a photonic crystal hydrogel film which comprises Fe 3 O 4 Nanoparticles and polyacrylamide-methylene bisacrylamide-N, N' -bis (acryloyl) cystamine hydrogel, and preparation method thereof 3 O 4 The nano particles, acrylamide, methylene bisacrylamide, N' -bis (acryloyl) cystamine and a photoinitiator are uniformly dispersed in an organic solvent, a magnetic field is loaded, and a photonic crystal hydrogel film is obtained after ultraviolet light irradiation, and can be applied to naked eye detection or a biomolecule sensor. The invention makes Fe by loading magnetic field 3 O 4 The nano particles are arranged in a one-dimensional chain shape and are polymerized by ultraviolet irradiation, the film is monochromatic and pure, has the response capability of reduced glutathione, has good specificity to the reduced glutathione and high sensitivity, can be applied to naked eye detection, can solve the problems of expensive detection and complex operation of the reduced glutathione, and provides a new way for the detection of the reduced glutathione in aqueous solution. |
