Preparation method and application for photoelectrochemical parathion sensor based on two-dimensional nanometer light-sensitive material

摘要: The invention discloses a preparation method for photoelectrochemical parathion sensor and belongs to the technical field of novel nanometer functional materials biosensors.According method, two-dimensional light-sensitive material Mn-MoO3/TiO2@g-C3N4 is prepared first, loaded with antibody according good biocompatibility large specific surface area material, then alkaline phosphatase fixed by cross linking action glutaraldehyde; during detection, can catalyze L-ascorbic acid-2-trisodium phosphate salt APP in-situ production acid AA, an electron donor provided photoelectric influence quantitative combination specificity antigen on transmission capability utilized, so that current intensity lowered accordingly, finally biosensor which low in cost, high sensitivity, specificity, quick easy prepare free marks used detecting prepared.
