Dear Colleagues,

Diabetic mellitus is a metabolic disease marked by high levels of blood glucose that can lead to serious complications including kidney failure, blindness, cardiovascular disease, and premature death. The World Health Organization estimates that the number of people with diabetes is approximately 350 million with projections of 590 million by 2035. In order to prevent diabetic complications, diabetics must contain tight glycemic control by monitoring their glucose levels throughout the day, typically through fingerprick blood glucose biosensors. Fingerprick glucose biosensing is quite arduous to the diabetic patient, requiring hand washing, a finger prick with a lancet, and blood application to a test strip which is often times painful, publicly embarrassing, costly to the patient, and limited to one-time snapshot measurements of blood glucose levels.

This Special Issue is devoted to exploring new advances in glucose biosensing that seek to overcome the drawbacks of conventional fingerprick glucose biosensing. Glucose biosensors that are geared towards obtaining patient blood glucose levels by monitoring other sampling medium, such as tears, saliva, and sweat, in a noninvasive or continuous fashion are particularly encouraged. Studies that use new or nonconventional materials to improve biosensor transduction (e.g., nanomaterials, such as graphene, carbon nanotubes, or metallic nanoparticles) or eliminate the need for biological agents (e.g., non-enzymatic biosensing) are also of interest. Research that changes the paradigm of glucose biosensing by presenting a completely new transduction element such as eye contact lenses that monitor glucose in tears or wearable tattoos/bandages that monitor glucose in sweat or subcutaneous fluid are of high interest. Manuscripts focused on diverse sensing modalities, including optical or electrochemical sensing, as well as those focused on cloud-based data management or the advancement of the Internet of Things with regards to glucose biosensing will also be accepted.

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. Chemosensors 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.
