Special Issue Information
Dear Colleagues,
Thanks to advances in science and technology, several artificial recognizers (AFRs) have been synthesized in recent years, opening a new chapter in bioassays and biosensors.
Aptamers are well-known examples of AFRs that are used for the detection of a wide range of targets, from heavy ions to cancer cells. The aptamer is an artificial probe widely used for the fabrication of biosensors for the determination and imaging of molecules, ions, cells, bacteria, etc. Peptide, nucleic acid (DNA and RNA) and peptide nucleic acid (PNA) probes are the most common aptamers used to fabricate aptasensors. Aptamers can selectively interact with their targets, preparing a unique opportunity for the detection of materials of biological phenomena such as cellular communication, mechanical tension forces in cells, etc. The aptamer/target interaction can be detected with the use of several transducers such as electrochemical and optical ones.
Results indicate that through the integration of nanomaterials with aptamers, the analytical performance of sensors such as the limit of detection and linear range can be improved.
This Special Issue intends to collect novel research on sensing technologies with the potential to be used for the fabrication of aptamer-based sensors in real samples, including original papers describing novel biosensors for the detection of biomarkers, cancer cells, bacteria, viruses, DNA or RNA fragments, and water and soil pollution components. Review articles should address recent advances in aptamer sensor technologies.
We look forward to receiving your contributions.

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.
