“…The creation of an electrochemical immunosensor for the sensitive, specific, and easy detection of anthrax protective antigen (PA) toxin in picogram concentrations was developed by Sharma et al 31 in 2015. Bismuth/heavy metal alloys were previously used for the creation of distinct stripping peaks, a broad cathodic potential range, and high sensitivity.…”

During the past year, disease has shown us the iron grip it can hold over a population of people. Health systems can be overwhelmed, economies can be brought into recession, and many people can be harmed or killed. When weaponized, diseases can be manipulated to create a detriment to health while becoming an economic burden on any society. It is consequently prudent that easy detection of bioweapons is available to governments for protecting their people. Electrochemical sensing displays many distinct advantages, such as its low limit of detection, low cost to run, rapid generation of results, and in many instances portability. We therefore present a wide array of electrochemical sensing platforms currently being fabricated, a brief summary of Class A bioweapons, and the potential future of bioweapon detection and biosafety.

“…are being widely utilised for electrochemical bio-sensing. A highly sensitive and specific electrochemical immunosensor consisting of bismuth nanoparticles (BiNPs) nanocomposites modified glassy carbon electrode and cadmium ion loaded titanium phosphate signal tag has been developed for detection of anthrax PA toxin 58 . Gold and palladium bimetallic nanoparticles loaded on boron-nitride nanosheets were explored as catalytic label for the development of electrochemical immunosensor for detection of B. anthracis with the minimum detection limit of 1 pg/mL 59 .…”

Recently, threat from biological warfare agents (BWAs) has emerged as the foremost national and global security challenge because of their simple and cheap production, easy dispersal, complicated detection, expensive protection and psychological, economical and social impact. Early detection and identification of BWAs during intentional biological event is essential to initiate corrective emergency responses for management of such incidents. Efforts are being made across the globe for development of state of the art technologies and systems for detection and identification of BWAs. However, till date there is no single system which can detect all the bio-threat agents. In the present review, we describe the currently available techniques and systems for detection and identification of these agents. The basic identification techniques including biological culture, immunological methods, nucleic acid based detection, MALDI-TOF MS, cellular fatty acid profiling and flow cytometry based detection are presented. Detection of BWAs with bio-sensors, surface plasmon resonance, biological detectors, and stand-off detection systems is also summarized. However, despite of availability of several techniques and tools, no full proof system is available for detection/identification of all the BWAs.

“…Cadmium oxide (CdO) is a semiconductor of group II–VI with the direct bandgap of about 4.1 eV in room temperature and exciton binding energy of about 75 meV having a polycrystalline nature with n‐type semiconducting behaviour. It is known for its high electrical conductivity and optical transmission properties which tend to possess enhanced anti‐cancer and antibacterial activities [9–11].…”
