Tailoring heterostructured Bi2MoO6/Bi2S3 nanobelts for highly selective photoelectrochemical analysis of gallic acid at drug level

Since some officinal plants are full of antioxidants, these crude drugs often use gallic acid (GA) as the quality criterion in accordance with Chinese Pharmacopeia. An ingenious Bi2MoO6/Bi2S3 photoelectrochemical platform was successfully involved in selective GA analysis to guarantee drug safety.214
