Special Issue Information
Dear colleagues,
Biosensors with high selectivity and sensitivity can monitor important biomarkers in body fluids, which have critical applications in biomedical research, such as diseases diagnosis, health condition monitoring, and environmental monitoring. Developing biosensors that provide accurate, real-time information of one or multiple analytes is at the heart of next-generation medical devices for personalized medicine, such as point-of-care measurements, wearable sensors, and implantable bioelectronics. Field-effect transistors (FETs) have unique properties and advantages toward applications for biosensing, including label-free detection, low detection limits, real-time sensing, and straightforward integration with standard semiconductor processing. FET biosensors are typically constructed by immobilizing environmental sensitive chemical and biological molecules on the surfaces of semiconducting channels or gate electrodes, such as pH-sensitive molecules, antibodies, enzymes, and aptamers. Upon interactions with target molecules, receptors induce electronic signals in FETs, such as changes in channel conductance, source-drain current, threshold voltages, and device capacitance. Novel fabrication approaches, including different device designs, synthesis of novel materials, and unconventional fabrication approaches, have been proposed to enable advanced applications needed for biosensors. Accordingly, this Special Issue seeks to showcase research papers, short communications, and review articles that focus on fabrication and application of FET biosensors, such as novel fabrication and design of FET biosensors, different detection mechanism based on FET biosensors, and advances in FET applications for biomedical applications.

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. Micromachines 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 2100 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.
