Biosensors Based on Two-Dimensional Materials

Dear Colleagues,

In 1985, the world market for biosensors was estimated at USD 5 million. Today, it exceeds the figure of USD 28,000 million. This extraordinary success is undoubtedly due to the strategic nature of their use, resulting from the combination of basic research with the eminently practical objective of generating wealth and improving the quality of life. An additional attraction for biosensor research lies in its multidisciplinary nature, that demands not only experience in chemistry, physics, biology, or engineering but also deep knowledge in the areas where biosensors are applied: in pharmaceutical fields, environmental and food control, as well as clinics and healthcare. Related with the latter, the early diagnosis of any disease is a key element that determines the success of its treatment and cure. Being able to conduct rapid and reliable analytic tests at a very low cost would allow widespread and early diagnosis to be possible for the general population, thus contributing to the globalization of healthcare. Two-dimensional materials could be the missing link in the chain that would allow this dream to become a reality within a short period of time: recent results show that biosensors based on two-dimensional materials could make analytical results available at the patient’s bedside or a physician’s office within few minutes, all for a low cost and with very low limits of detection. The nanosized nature of nanomaterials and their unique chemical and electrical properties can improve patient care by making the sensors minimally invasive and extremely sensitive and, at the time, amenable to high-throughput screening, real-time analysis, and label-free detection together with a low limit of detection (LOD) and low sample volume requirements for analysis. This Special Issue is dedicated to the advanced and emerging concepts and technologies of bioelectric sensors based on two-dimensional materials. Topics include, but are not restricted to, electrochemical sensors, optical sensors, and field effect transistor methods. Also of interest are innovative approaches offering a high-throughput analytical capacity, point-of-care/portable and wireless instrumentation, and intelligent bioelectric sensing platforms. Research papers, short communications, and reviews are all 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.
