Special Issue Information
Dear Colleagues,
Photoelectrochemical (PEC) biosensors have emerged as transformative tools in analytical science, combining the sensitivity of photoelectrochemistry with the specificity of biorecognition elements. These systems leverage light-induced electron transfer processes to detect biological and environmental analytes, offering advantages such as high sensitivity, rapid response, and miniaturization potential. Recent advancements in material science, particularly in porous and semiconductor-based photoactive materials, have significantly enhanced PEC biosensor performance by optimizing light absorption, charge separation, and surface reactivity.
This Special Issue invites contributions that explore cutting-edge developments in PEC biosensors, focusing on their design, functionalization, and applications in healthcare, environmental monitoring, and biomimetic sensing. Topics of interest include but are not limited to the following:
- Innovative Photoactive Materials: The design of semiconductors, quantum dots, and porous frameworks (e.g., metal–organic frameworks, hydrogels) for enhanced PEC activity.
- Surface Engineering: Strategies to improve bioreceptor immobilization, antifouling properties, and stability under operational conditions.
- Integrated Systems: The development of wearable, implantable, or self-powered PEC biosensors for the real-time monitoring of biomarkers, pathogens, or pollutants.
- Environmental and Biomedical Applications: The detection of environmental contaminants (e.g., heavy metals, pesticides) and disease biomarkers (e.g., proteins, nucleic acids) with high selectivity and low detection limits.
- Advanced Signal Transduction Mechanisms: exploring neuromorphic or AI-driven data processing to mimic biological sensory pathways.
We welcome original research articles, reviews, and perspectives that highlight novel methodologies, mechanistic insights, or applications of PEC biosensors. Submissions should emphasize scalability, reproducibility, and relevance to real-world challenges.

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.
