Special Issue Information
Dear Colleagues,
The application of silicon nanostructures in sensorics has many advantages, such as high sensitivity, fast response, low cost, and the ability for multiple uses. Additionally, silicon nanostructures can be obtained through various methods, such as electrochemical or metal-assisted etching of silicon, gas-phase deposition, and thermal treatment, allowing for the tuning of their morphology and properties to create materials with specific functional characteristics.
Sensors based on silicon nanostructures can be used for the sensitive detection of low concentrations of various gases, liquids, biomolecules, and bio-objects due to their large specific surface area. They can also detect changes in the surrounding environment, such as temperature and humidity. Moreover, sensor response can be obtained through various mechanisms, with the main ones being changes in electrical conductivity or changes in optical properties.
Silicon nanostructures can be used to create composite materials based on silicon and noble metal nanoparticles, which can improve detection sensitivity and selectivity. Such silicon-based plasmonic sensors can be used for the ultra-sensitive and fast detection of biomolecules and other analytes.
This issue of the IJMS is dedicated to research on the use of silicon nanostructures in sensing, which has great potential for scientific, medical, and industrial applications. Further development of this technology may lead to the creation of rapid, accurate, and efficient sensors for various fields of application.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
