WO3 nanoparticles decorated core–shell TiC–C nanofiber arrays for high sensitive and non-enzymatic photoelectrochemical biosensing

A photoelectrochemical biosensing platform based on a WO3 decorated highly conductive TiC-C NF electrode is fabricated and boasts a low detection limit of 1.12 × 10(-8) M (S/N = 3) and high sensitivity for glucose detection at a visible light irradiation density of 50 mW cm(-2).
