Research topics from publications: A high-performance photoelectrochemical sensor based on CdS–Au composite nanomaterials and localized surface plasmon resonance for ultrasensitive detection of ascorbic acid; An ultra-sensitive PEC aptasensor based on BiOI/Cu2O@Au heterojunction nanomaterials for the detection of OTA; Visible light-activated signal amplification PEC aptasensor for ultrasensitive zearalenone detection based on double Z-type BiOI/g-C3N4@Au/Bi2S3 heterojunctions; A novel and ultrasensitive PEC aptasensor based on precisely controlled CdS/80NiO-Au heterojunction nanomaterials by ALD for detection of E. coli O157: H7; Novel dual type-II WO3/g-C3N4/Cu2O-Au heterojunction-based photoelectrochemical aptasensor for ultra-sensitive AFB1 detection in Astragalus matrix. Representative work: . In addition, the mechanism of the PEC sensor based on CdS-Au composite nanomaterials for ultrasensitive AA detection was discussed. Lastly, the self-constructed PEC sensors have been successfully applied in detecting AA in vitamin C tablets and actual blood samples, meeting the detection criteria required by the Chinese Pharmacopoeia (CP, 2020 edition). The self-fabricated PEC sensors in this paper are expected to be used for quality assessment of AA-related drugs and diagnosis of relevant diseases
