Recent Progress in Photoelectrochemical (PEC) Biosensors and Bioassays

Dear Colleagues,

Increasing evidence has shown that specific biomarkers are helpful for the early detection, prognosis, and efficient evaluation of cancer. Highly sensitive sensing technologies (based on biomarkers derived from cerebrospinal fluid, blood, saliva, urine, or tissues and organs) can effectively measure and identify changes in clinically meaningful outcomes. Photoelectrochemical (PEC) detection, as a promising and burgeoning technique, has gained much attention in the analytical community by inheriting the advantages of both electrochemical and optical techniques. The photo-driven electrochemical response is an essential part of PEC analysis, making it indispensable in amplifying the corresponding PEC signals for sensitive detection. This Special Issue, entitled “Recent Progress in Photoelectrochemical (PEC) Biosensors and Bioassays”, focuses on topics that include, but are not limited to, the following: design and engineering of photoactive materials, label-free and label-based PEC bioassays, PEC sensing devices, and detection modes.

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. Biosensors is an international peer-reviewed open access monthly 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 2200 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.
