Photoelectrochemical (PEC) biosensing plays an important role in the advancement of analytical chemistry, such as the DNA biosensors, immunosensors, aptasensing and enzymatic biosensors, owing to the advantages of high sensitivity, low background signal, easy operation and inexpensive instrument. Specifically, the high-performance of PEC sensing platforms generally lies on the photoelectrodes, most of which are prepared with photosensitive nanomaterials. Because of their merits of high specific surface area, fast electron transfer rate, good light harvest property and good biocompatibility, the rational design of photosensitive nanomaterials is one of the most critical steps, which is responsible for the highly sensitive and selective PEC biosensing.
The goal of this Research Topic is to address the recent advances in effective detection methods such as biomarker detection, heavy metal ion detection, and bacterial detection through PCE sensing based on nanomaterials, thus promoting the wide application of PCE sensing in diseases, environment, food and other fields. We would like to cover advances in photosensitive nanomaterials in terms of their synthesis, characterization, modifications and applications in PEC biosensors. The impact of using photosensitive nanomaterials on improving the sensitivity, selectivity and biocompatibility of the photoelectrochemical biosensors will be covered.
We welcome various article types, including Original Research, Mini Reviews and Perspectives on themes, but not limited to:
• Inorganic, organic or hybrid semiconductors and their photoelectrochemical biosensing applications
• Nanoparticles and their use in photoelectrochemical signal amplifications in biosensors
• Heterojunction electrode platform for superior photoelectrochemical biosensing

• Nanomaterials-based photoelectrochemical immunoassays
• Integreated devices based on photoelectrochemial biosensing
• Photoelectrochemical DNA biosensors base on nanomaterials
• Multi-channel or multi-flux PCE sensing based on nanomaterials
