In this work, a novel photoelectrochemical (PEC) aptasensor was developed for the sensitive detection of aflatoxin B1 (AFB1) based on a resonance energy transfer strategy between the Ce-TiO 2 @MoSe 2 heterostructure and Au nanoparticles (AuNPs). The Ce-TiO 2 @MoSe 2 composite was obtained by growing...
