Novel Ti₃C₂T_x MXene nanozyme with manageable catalytic activity and application to electrochemical biosensor.

ABSTRACT: In this work, Ti₃C₂T_x MXene was identified as efficient nanozyme with area-dependent electrocatalytic activity in oxidation of phenolic compounds, which originated from the strong adsorption effect between the phenolic hydroxyl group and the oxygen atom on the surface of Ti₃C₂T_x MXene flake. On the basis of the novel electrocatalytic activity, Ti₃C₂T_x MXene was combined with alkaline phosphatase to construct a novel cascading catalytic amplification strategy using 1-naphthyl phosphate (1-NPP) as substrate, thereby realizing efficient electrochemical signal amplification. Taking advantage of the novel cascading catalytic amplification strategy, an electrochemical biosensor was fabricated for B
