A dandelion-like BiOBr-Bi2MoO6-based photoelectrochemical sensor for highly sensitive detection of acetaminophen.

. Under visible-light irradiation, AP acted as an electron donor to consume photogenerated holes, thereby suppressing electron-hole recombination and enhancing the photocurrent response. Under optimized conditions, the proposed PEC sensor exhibited a linear range of 0.06-3.5 μM and a low limit of detection (LOD) of 0.01 μM (S/N = 3). This work provides promising insights for the design of novel photoactive materials and their application in the analysis of biomolecules.
