Photoelectrochemical biosensing platforms for tumor marker detection

Recent advances in electron manipulation of nanomaterials for photoelectrochemical biosensors

“…1), i.e., the generation of excited electrons in PEC active materials, introduction of specific materials for the formation of new electron transfer pathways, and the separation of excited electrons in semiconductors. Although there are some excellent reviews about PEC sensing from other perspectives, such as, architectures of PEC biosensing, 11,48,49 summary of signal amplification strategies, 50,51 PEC active materials 17,52,53 or application of PEC biosensors, 54,55 to our knowledge, systematically summarizing the construction mechanism of PEC biosensors from the perspective of the electron transfer process has not been reported yet. We hope this review will enhance the interest of readers leading to further development of PEC biosensing.…”

Ultrasensitive photoelectrochemical biosensing platform based target-triggered biocatalytic precipitation reactions on a flower-like Bi2O2S super-structured photoanode

“…[15][16][17][18] In essence, PEC analysis is a next-generation sensing technique for inherited electrochemistry under additional conditions (photon excitation), and naturally exhibits the advantages of electrochemistry assays such as controllable cost, simple instrument construction and high sensitivity. 19 Although much progress has been made in developing efficient PEC sensing strategies, there are still some limitations in developing more efficient and accurate bioanalytical methods.…”

Facile and sensitive photoelectrochemical detection of kojic acid in food products: a general strategy for immobilization-free analysis of enzyme inhibitors

“…Thanks to these unique properties, PEC has been widely applied in disease-related bioanalysis, environmental analysis and food contaminants analysis. 12 However, there's no report addressing PEC detection for KA so far.…”
