“…Of the many detection methods, fluorescence-based methods and materials are among the most promising tools for the detection of (nitro-)explosives due to their high sensitivity and selectivity, fast response time, simplicity, portability, and, in most cases, low cost. Therefore, fluorescence-based sensory materials can be easily and effectively integrated into sensing devices for remote (nitro-)explosive detection, for instance, the well-known Fido explosive detector [ 145 ], as well as other types of “electronic noses” [ 146 , 147 ]. In addition, some simpler devices and approaches can be introduced, for instance, mobile-phone-based explosive detection systems [ 148 ] or computer-vision-based algorithms [ 149 ].…”

Methods for the remote detection of warfare agents and explosives have been in high demand in recent times. Among the several detection methods, fluorescence methods appear to be more convenient due to their low cost, simple operation, fast response time, and naked-eye-visible sensory response. For fluorescence methods, a large variety of fluorescent materials, such as small-molecule-based fluorophores, aggregation-induced emission fluorophores/materials, and supramolecular systems, have been reported in the literature. Among them, fluorescent (bio)polymers/(bio)polymer-based materials have gained wide attention due to their excellent mechanical properties and sensory performance, their ability to recognize explosives via different sensing mechanisms and their combinations, and, finally, the so-called amplification of the sensory response. This review provides the most up-to-date data on the utilization of polymers and polymer-based materials for the detection of nitroaromatic compounds (NACs)/nitro-explosives (NEs) in the last decade. The literature data have been arranged depending on the polymer type and/or sensory mechanism.

“…Recent advances in other scientific areas or approaches combined with miniaturization and hand portability have led to the development of a wide range of sensing EN systems based on different technologies. Therefore, EN have benefited from developments in optics (e.g., fiber optic based detectors), in piezoelectrics (surface acoustic wave (SAW) detectors), in fluorescent polymers, in nanotechnology (gold nanoparticle based chemiresistors), and in microelectromechanical systems (MEMS). , From a wider perspective, electronic noses can also be considered as analytical instruments with machine olfaction capabilities (gas detection, chemical determination, and quantification), alongside mass spectrometry (MS) based devices, ion mobility spectrometers (IMS), and gas chromatography (GC). ,,, These technologies are described in detail in sections , , and .…”

Border control for homeland security faces major challenges worldwide due to chemical threats from national and/or international terrorism as well as organized crime. A wide range of technologies and systems with threat detection and monitoring capabilities has emerged to identify the chemical footprint associated with these illegal activities. This review paper investigates artificial sniffing technologies used as chemical sensors for point-of-use chemical analysis, especially during border security applications. This article presents an overview of (a) the existing available technologies reported in the scientific literature for threat screening, (b) commercially available, portable (hand-held and stand-off) chemical detection systems, and (c) their underlying functional and operational principles. Emphasis is given to technologies that have been developed for in-field security operations, but laboratory developed techniques are also summarized as emerging technologies. The chemical analytes of interest in this review are (a) volatile organic compounds (VOCs) associated with security applications (e.g., illegal, hazardous, and terrorist events), (b) chemical "signatures" associated with human presence, and
