Smart Electromagnetic Sensors: Optical, Microwave, and Terahertz Technologies for Chemical and Biological Applications

Dear Colleagues,

Electromagnetic sensors are at the forefront of modern analytical technologies, enabling high-sensitivity, non-invasive detection of chemical and biological agents. Advances in optical, microwave, and terahertz sensing have revolutionized fields such as biomedical diagnostics, environmental monitoring, and industrial safety. The integration of novel materials, cutting-edge fabrication techniques, and artificial intelligence has further enhanced their precision, selectivity, and real-time capabilities.

This Special Issue aims to highlight the latest theoretical and experimental research in electromagnetic sensors for chemical and biological applications. We invite contributions on a wide range of topics, including but not limited to the following:

• Optical fiber sensors, plasmonic sensors, and photonic biosensors;
• Microwave and terahertz sensors for chemical and biological detection;
• Novel sensing materials, metamaterials, and nanostructures in optical, microwave, and THz range;
• Integration of machine learning and AI-driven sensor optimization;
• Lab-on-a-chip and point-of-care sensing platforms;
• Multimodal sensing approaches combining optical and microwave techniques;
• Real-world applications in healthcare, food safety, environmental monitoring, and security.

We welcome original research articles, reviews, and perspectives that contribute to the advancement of electromagnetic sensing technologies.

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 250 words) can be sent to the Editorial Office for assessment.

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. Chemosensors 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 2000 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.
