Editorial for the SI of PEC Bioanalysis In 1839 the seminal discovery of photoelectric effect by Edmond Becquerel has inaugurated a new era of photoelectrochemical (PEC) science. And the modern PEC science has been actively developing in different disciplines. In recent years increasing attention has been paid to the integration of PEC science with biochemical measurements, which, eventually, leads to the generation of an innovative field of PEC bioanalysis. From its very beginning, PEC bioanalysis has promptly becoming a subject of new research hotspots because of its attractive properties and great potential in future biological analysis. With the aid of semiconductive materials, this new detection technique offers great promise for developing elegant and versatile miniaturized analyzers compatible with future requirements. After enormous efforts that have been devoted, significant progresses have been achieved in its fundamentals, signaling strategies and also bioanalytical applications. Now, more methods to advanced PEC bioanalysis are reported in growing scholarly papers. As Editors, we strongly feel that it is essential to highlight the stateof-the-art in the dynamically developing field of PEC bioanalysis in the

Journal of Electroanalytical Chemistry. In this Special Issue, we have tried to select a range of papers which represent the current bioanalytical exploitations using this technique. For example, Zheng et. al and Wang et. al developed the plasmonic PEC monitoring of Ca2+ from living cardiomyocytes and sub-picomole sensing of L-cysteine, respectively. Lei and Wang et. al prepared carbon nitride nanosheets sensitized quantum dots and hemin sensitized nanoporous NiO, respectively, as novel photocathodes for PEC biosensing. Besides, Yu et. al proposed “signal-off” PEC DNA sensing strategy based on target dependent aptamer conformational conversion and Wen et. al reported the cathode PEC immunoassay based on analyte-induced formation of exciton trapping. Overall, the works included in this special issue cover the cutting-edge works of the exploiting and applications of PEC bioanalysis. And we are quite sure that this special issue will be useful for the analytical chemists in this field.
