Special Issue Information
Dear Colleagues,
Photoelectrochemical (PEC) sensing is an analytical technique that combines the principles of photoelectrochemistry and traditional sensing methods to detect and quantify bio(chemical) substances. It leverages the interaction between light and materials to generate an electrical signal, which is correlated with the concentration of the analyte. PEC sensors typically involve a photoactive material, such as a semiconductor, that absorbs light and generates charge carriers (electrons and holes). These carriers participate in redox reactions at the electrode surface, thus producing a measurable current. The method offers high sensitivity due to the unique setup consisting of two separate energy forms, that is, using light as the excitation source and electricity as the detection signal. Applications of PEC sensing are diverse, ranging from environmental monitoring and food safety to clinical diagnostics and biochemical analysis.
This Special Issue will cover the system, instruments, methods, and photoactive and bio-sensitive materials used to construct PEC sensors with various bio(chemical) sensing applications, such as investigations of living cells, organoids, or tissues, as well as detections of ions, bio(chemical) molecules, or metabolites.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
