Special Issue Information
Dear Colleagues,
We invite you to contribute to this Special Issue concerning transistor‐based biosensors. Electron biosensors based on field-effect transistors (FETs) are universal, high-sensitivity, real-time, label-free platforms for biomolecular detection. First of all, these sensors are requested in the field of medical diagnostics for point‐of-care testing of various analytes (DNA, RNA, proteins, and others). Different types of transistors made of different materials To date, the development of such devices has reached the stage of commercialization. Reproducibility and stability of the sensor response are the key issues hindering their large-scale deployment/application. The increase in sensitivity is an acute issue, since most disease markers are low-copy and their content in human biofluids, especially at the early stage of diseases, is at the femto- and subfemtomolar level. The topics of this Special Issue allow you to present various approaches aimed (1) to reduce the limit of detection and increase the linear range of target detection for early diagnosis and treatment prediction of diseases, and (2) to increase the stable device performance. Topics may include, but are not limited to:
- Target delivery of analytes to the sensor surface;
- Minimizing non-specific adsorption;
- Overcoming Debye length limitations for biomolecule sensing;
- Surface functionalization and characterization;
- Signal-enhanced methods;
- Comparison of perfection of sensors on the basis of different materials.
Original experimental and theoretical papers and reviews are welcome.

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 2700 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.
