In today's world there is a great need for sensing methods as tools to provide critical information to solve today's problems in security applications. Real time detection of trace chemicals, such as explosives, in a complex environment containing various interferents using a portable device that can be reliably deployed in a field has been a difficult challenge. A hybrid nanosensor based on the electrochemical reduction of trinitrotoluene (TNT) and the interaction of the reduction products with conducting polymer nanojunctions in an ionic liquid was fabricated. The sensor simultaneously measures the electrochemical current from the reduction of TNT and the conductance change of the polymer nanojunction caused from the reduction product. The hybrid detection mechanism, together with the unique selective preconcentration capability of the ionic liquid, provides a selective, fast, and sensitive detection of TNT. The sensor, in its current form, is capable of detecting parts per trillion level TNT in the presence of various interferents within a few minutes. A novel hybrid electrochemical-colorimetric (EC-C) sensing platform was also designed and fabricated to meet these challenges. The hybrid sensor is based on electrochemical reactions of trace explosives, colorimetric detection of the reaction products, and unique properties of the explosives in an ionic liquid (IL). This approach affords not only increased sensitivity but also selectivity as evident from the demonstrated null rate of false positives and low detection limits. Using an inexpensive webcam a detection limit of part per billion in volume (ppbV) has been achieved and demonstrated selective detection of explosives in the presence of common interferences (perfumes, mouth wash, cleaners, petroleum products, etc.). The works presented in this dissertation, were published in the Journal of the American Chemical Society (JACS, 2009) and Nano Letters (2010), won first place in the National Defense Research contest in (2009) and has been granted a patent (WO 2010/030874 A1). In addition, other work related to conductive polymer junctions and their sensing capabilities has been published in Applied Physics Letters (2005) and IEEE sensors journal (2008).

This reference reviews the reported literature on new approaches of nanocomposite material preparation and their applications in the development of physical, chemical, electrochemical, biological, fluorescence and colorimetric sensors. Sensor nanomaterials have been extensively used to amplify signals in the detection of a range of chemicals including toxic gases, biochemical nutrients, ions, explosives, pesticides and drugs to name a few. 14 chapter contributions highlight state-of-the-art sensors in recent years by outlining the synthesis, role and progress of nanocomposite materials in fabricating flexible and multifunctional sensing platforms in sensor technologies. Chapters first introduce the reader to nanocomposite materials and their role in making a wide array of sensors including metal-organic, graphene-based and polymeric sensors. The chapters then progress into applications of sensors for the detection of chemicals such as blood glucose, heavy metal and other toxic ions, hydrazine, humidity and explosive. Each chapter explains the required materials for electrodes and material components for a specific sensor platform with additional information about sample collection, threshold values and perspectives where appropriate. The book is intended as a compilation of knowledge for designing novel nanocomposite materials to be used as sensing platforms in sensor technologies. It serves as an informative resource for a broad range of readers including graduates and post-graduates, Ph. D. scholars, faculty members and professionals working in the area of material science, the healthcare industry, biological sciences, medical sciences, and environmental sciences.

The results of this study demonstrate that remotely-deployable submersible sensors are capable of monitoring explosive compounds both temporally and spatially in groundwater and can be more cost effective than conventional sampling and analysis. Such new remote-sensing capability can bring significant changes to the way in which nitro-based explosives are monitored. At this time, this technology can be deployed in standard groundwater wells that are 1.5 inches or greater in diameter. Future modification of the sensor probe could decrease the probe size to less than 3/4 inch to accommodate installation with minimally invasive direct-push technologies, ml such as cone penetrometer or GeoProbe system. Furthermore, the sensor measurement frequency can be easily changed from a remote location, enabling the investigator to tailor the measurement cycle to the speed at which the parameter in question is or may be changing. During the course of this SERDP SEED project, various working electrode materials and voltammetric waveforms were compared, and relevant experimental parameters were optimized. Based on initial testing we developed a submersible electrochemical probe, using a carbon-fiber electrode assembly, connected to a 50-foot-long shielded cable, for the real-time monitoring of nitro-organic explosives in natural water. The facile reduction of the nitro moiety group allowed convenient and rapid square-wave voltammetric measurements of trace levels of nitroaromatic explosives (TNT, TNB, and Tetryl) down to levels of 50 to 100 pb.
