| titleOfInvention | Photonic crystal heavy metal sensor with immobilized enzyme and preparation method thereof |
| abstract | The invention discloses a photonic crystal heavy metal sensor with immobilized enzyme and a preparation method thereof, and the method comprises the following specific steps: firstly, preparing a prepolymerization solution containing a functional monomer, a cross-linking agent, ethanol and a photoinitiator, filling the prepolymerization solution into gaps of photonic crystal colloidal particles, and placing the photonic crystal colloidal particles under an ultraviolet lamp for polymerization; after polymerization is completed, etching by hydrofluoric acid to obtain the inverse protein structure photonic crystal sensor with pH responsiveness; inserting one side of the photonic crystal sensor, which is not provided with the photonic crystal organic glass sheet, into the polydopamine solution for placement; and taking out the sensor, and inserting one side with the polydopamine coating into a urease solution with a certain concentration to fix urease to obtain the photonic crystal heavy metal sensor with the immobilized enzyme. Compared with the traditional detection method, the inverse opal structure photonic crystal sensor with the immobilized enzyme prepared by the invention is simpler and more convenient to operate, better in stability, higher in sensitivity and faster in response speed. |
