Special Issue Information
Dear Colleagues,
Biosensors couple a bio-receptor to a transducer and a physico-chemical detector in order to transform a specific biological signature or activity into a digital signal. Transducers can be external to the cells, like in electrochemical methods, or can be incorporated into the cells, such as in optogenetic sensors. The detected biological event can be resolved in space at different levels, ranging from subcellular domains and organelles to individual cells and entire cell-population responses. In addition, the time resolution also varies largely between the different techniques available.
Here, we focus on biosensors to measure processes occurring in live cells. Different events can be measured that reflect the cell status or the response to a specific challenge, such as electrical activity, ion concentrations, second messenger dynamics, changes of cell volume and morphology, pH, metabolic and redox state, cell-cycle progression and proliferation, cell death and apoptosis, cell–cell interaction, hormones or neurotransmitters release, and mechanical strain. Optical and electrochemical biosensors may be applied to primary cells, cell lines, iPSCs, and in vivo. Furthermore, they are also a versatile tool in 3D cultures and organoids.
Monitoring biological events in live cells is important not only for basic research but also for drug discovery and development, toxicity screening, disease modelling, as well as clinical diagnostics and treatment. In this context, scientific progress is continuing to increase the content and/or throughput of biosensor-based screening, miniaturization, and application in vivo.

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.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
