Sensing of Deadly Toxic Chemical Warfare Agents, Nerve Agent Simulants, and their Toxicological Aspects provides a general overview of the development and performance of different novel molecular frameworks as potent vehicles for sensing Chemical Weapons (CWs). The chapters are contributed by leading researchers in the areas of materials science, medical science, chemical science, and nanotechnology from industries, academics, government and private research institutions across the globe. It covers cover topics such as inorganic nanocomposites, hyperbranched polymers, and graphene heterojunctions for effective sensing of CW agents. This book is a highly valuable reference source for graduates, post-graduates, and research scholars primarily in the fields of materials science, medicinal chemistry, organic chemistry, and nanoscience and nanotechnology. In addition, almost all analytical techniques will be discussed, making this a first-rate reference for professors, students, and scientists in many industries. Provides an efficient, reliable, and highly versatile approach for the synthesis of different molecular systems suitable for diversity-oriented strategies, structure-activity studies and molecular tailoring for the sensing of chemical warfare agents Goes into depth on new binary organogels, discrete carbon nanomaterials (CNMs) and molecularly imprinted polymers (MIPs) and has endowed electrochemical chemosensors (ECCSs) with high selectivity and sensitivity towards the detection of chemical warfare agent Highlights in detail the detection of CWs by composite optical waveguide sensors, and describes disposable biofilm biosensors for sensitive detection of biotoxicity in water with treatment of nerve agent poisoning

Presents a comprehensive and interdisciplinary review of the major cutting-edge technology research areas—especially those on new materials and methods as well as advanced structures and properties—for various sensor and detection devices The development of sensors and detectors at macroscopic or nanometric scale is the driving force stimulating research in sensing materials and technology for accurate detection in solid, liquid, or gas phases; contact or non-contact configurations; or multiple sensing. The emphasis on reduced-scale detection techniques requires the use of new materials and methods. These techniques offer appealing perspectives given by spin crossover organic, inorganic, and composite materials that could be unique for sensor fabrication. The influence of the length, composition, and conformation structure of materials on their properties, and the possibility of adjusting sensing properties by doping or adding the side-groups, are indicative of the starting point of multifarious sensing. The role of intermolecular interactions, polymer and ordered phase formation, as well as behavior under pressure and magnetic and electric fields are also important facts for processing ultra-sensing materials. The 15 chapters written by senior researchers in Advanced Sensor and Detection Materials cover all these subjects and key features under three foci: 1) principals and perspectives, 2) new materials and methods, and 3) advanced structures and properties for various sensor devices.
