Special Issue Information
Dear Colleagues,
The aim of this Special Issue is to collect recent research and developments in the field of protein/aptamer-based biosensors.
From the time when they were introduced by L.C. Clark, biosensors have dominated the scene of applied scientific research, opening new perspectives in diagnostic and medical techniques, thus improving the quality of life of healthy and sick people. The investigation about sensing and target materials, the biophysical and chemical aspects of signal transduction and amplification, as well as the wide possibility of custom-fit designs, have captured the attention of scientists from different expertise areas. Furthermore, the field of applications is not limited to biomedical research, but it covers, amongst others, environmental and energy harvesting issues. The use, at first, of proteins and, more recently, of aptamers as the sensitive part of the sensor has marked a turning point, improving the device sensitivity and selectivity, which are essential requirements for an early and secure detection. This kind of devices can, in principle, detect each kind of toxin, pathogen and, in general, molecule of interest. In doing so, they are supported by the most efficient trackers, i.e., specific proteins selected by millennia of natural evolution. Furthermore, when the products of a natural evolution are too expensive or ethically unsuitable, an “artificial evolution” can be called. Artificial evolution is the procedure (SELEX) for the selection of aptamers, which are synthetic molecules, so they do not pose ethical problems and are usually cheaper than proteins (antibodies, in particular). This can lead to a massive production, which is essential for a plausible entrance of biosensors in daily life.
The issue aims to collect updated reviews and also original contributions with both a theoretical and an experimental outlook. The manuscripts can deal with, but are not limited to, the following topics:
- Electrical and electrochemical biosensors;
- Aptasensors;
- Integrated biosensor systems (lab-on-a-chip);
- Biosolar cells;
- Noise reduction, control, and energy supply;
- Bio-field effect transistors.

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. Sensors is an international peer-reviewed open access semimonthly 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 2600 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.
Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
