Chemosensors for CBRNE (Chemical, Biological, Radiological, Nuclear, and Explosive) Security Applications

The threat of CBRNE (chemical, biological, radiological, nuclear and explosives) components is a major concern for global security. When devices or agents are used to cause mass disturbance and probably mass casualties, they are referred to as CBRNE incidents. One known example occurred after the 2001 attack on the World Trade Center in New York. Letters containing anthrax spores were sent to a number of public figures. While there were less than 30 people affected by the anthrax, including five deaths, it had a vast impact throughout the US. Mail delivery was disrupted, clerks were afraid to open mail, and reports of white powder were inspected frequently. Defense comprises passive protection, contamination avoidance, and CBRNE mitigation. There is currently a major security gap in the existing security flow that can be exploited by unwanted groups. Therefore there is an immense need for novel technological solutions that can be used for the detection and monitoring of CBRNE agents. The globalization process and open commercial goods transport has increased the need for monitoring thousands of shipments everyday worldwide. Major point-of-care systems that can be used in borderlines, airports, and seaports with high accuracy and fast response can be manifested by a variety of chemosensors.

This Special Issue will include recent developments and advances in all sensing tools developed for CBRNE detection, monitoring, and mitigation. Emphasis will be on the applications of innovative hybrid sensing modalities involving different receptor elements and different transducing solutions such as optical platforms, chemical layers, piezoelectric sensing, electrochemical, and other chemical detection systems. In addition wearable/attachable sensors are encouraged for point-of-care approaches.

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.
