New Advances and Applications in Biosensors for Biomolecules and Biochemicals

Dear Colleagues,

Biosensors have garnered considerable attention in recent years, both in academia and industry. Biosensors usually work by inducing biological or chemical reactions and generating signals on a transducing device. Theoretically, the signals are proportional to the concentration of the biomolecules. Successful examples of commercial biosensors include lateral flow pregnancy tests, electrochemical enzymatic glucose sensors, and, more recently, rapid antigen testing for SARS-CoV-2. Researchers have found innovative ways to develop biosensors for various biomolecules by combining powerful nanotechnology, state-of-the-art electronic devices, and advanced surface modification techniques. One of the main applications for biosensors is the detection of biomolecules or biochemicals that are early indicators of diseases (e.g., cancer) or other biological hazards. Biosensors can also be used in diverse applications such as environmental monitoring, food safety, defense, drug discovery, and implantable devices, to name a few. Because of this wide range of applications, biosensing technologies have become ubiquitous and are not confined to a specific niche. Our Special Issue aims to showcase the latest research in biosensor techniques based on the principles of electrochemistry, optical, piezoelectric, thermal, chemical, etc. This Special Issue will also cover sensor modification techniques based on biomolecules such as enzymes, antibodies, nucleic acids, and other affinity molecules. Finally, this Special Issue will allow researchers in the community to share their work on biosensor fabrication, in vitro and in vivo application, and biosensor instrumentation (including signal processing and transduction techniques) that encompass the detection of a variety of target biomolecules and biochemicals.

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 250 words) can be sent to the Editorial Office for assessment.

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. Eng 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 1400 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.
