Special Issue Information
Dear Colleagues,
Biochemical reactions occur inside the cell of organisms—not only due to the life process of organisms but also infection of viruses invading from outside the cell. The biochemical reactions can be modeled using chemical reactions of biomolecules. If the size of biomolecules ranges from several nanometers to a couple of 100 nanometers, the sensing tip of the sensing system (nanosensor) to detect biochemical reactions should be on a nanometer scale. The sensing tip with a well-designed geometry, shape, and surface (or interface) of a suitably chosen material (biocompatible material) is exposed to a specimen which detection targets (specific biomolecule) are dissociated in. The sensing tip is the finest component of nanosensors and is sensitive to any kind of responses to biochemical reactions—electric, electronic, magnetic, optical responses, etc. There may be various biocompatible materials and various designs and geometries depending on various responses. The sensing tip also takes a central role in converting detected biochemical reaction to a visible (macroscopic) signal. The detected responses are collected without involving noise or nonspecific reactions so that we can detect only specific biochemical reactions. Nanosensors are applicable to sensors of toxic gases, (biological) viruses, hazardous molecules, antigen–antibody reactions, and various biochemical reactions.
This Special Issue aims to cover all various aspects of the nanosensor and its related scientific and technical topics, including (but not limited to) functions, materials, geometries, any detailed designs of sensing tips, the conversion method to visible signals, specific biochemical reactions to be sensed, nonspecific noise, and so forth.

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.
