The invention discloses a porous carbon fiber loaded with transition metal oxide, a biosensor and a preparation method thereof, belonging to the technical field of biosensors. The porous carbon fiber loaded with transition metal oxide of the present invention is obtained by mixing a high molecular polymer, a transition metal salt and a solvent to obtain a spinning precursor solution, which is carbonized after electrospinning; the biosensor is fixed by the porous carbon fiber as a matrix made of boronic acid-based conductive polymers. The porous carbon fiber supporting the transition metal oxide of the present invention has a uniform mesoporous structure, and the pores are interconnected without subsequent treatment, and the preparation process is simple and the repeatability is high. The boronic acid-based conductive polymers are immobilized on the surface of porous carbon fibers supported by transition metal oxides, which can not only serve as a charge transport medium, but also promote the charge transport ability and specific selection of electrocatalytic reactions due to its own electrical conductivity and biorecognition properties. , and improve the response signal of electrocatalytic reaction. |
