“…Detection of DNT was possible at ppb levels, and the sensor could be recovered through UV irradiation. 143 Stefano et al compared the response of an electrochemical sensor for TNT using pure and acid-treated CNT-coated electrodes. The study found that residual metallic impurities in pure CNTs can improve the electrochemical response for TNT due to catalytic effects and increased surface roughness of the electrodes.…”

Explosive trace detection (ETD) technologies play a vital role in maintaining national security. ETD remains an active research area with many analytical techniques in operational use. This review details the latest advances in animal olfactory, ion mobility spectrometry (IMS), Raman and colorimetric detection methods. Developments in optical, biological, electrochemical, mass and thermal sensors are also covered in addition to the use of nanomaterials technology. Commercially available systems are presented as examples of current detection capabilities and as benchmarks for improvement. Attention is also drawn to recent collaborative projects involving government, academia and industry, to highlight the emergence of multimodal screening approaches and applications. The objective of the review is to provide a comprehensive overview of ETD by; highlighting challenges in ETD and providing an understanding of the principles, advantages and limitations of each technology and relating this to current systems.

This study provides overview of the different type of nanomaterials depending upon their size, and type, however focusing more on the Carbon Nanotubes. This review highlights the different synthesis and purification techniques and also the functionalization methods of Carbon Nanotubes (CNTs). In particular, molecular recognition application of Carbon Nanotubes is explored in the present study. The majority of data was collected for optical and electrochemical studies of Carbon Nanotube based platform for the detection of metal ions, anions, nitroaromatics, biomolecules and gas molecules since last two decades. This review ends with an outlook of future perspectives that could be employed in nano sensor fabrication. I believe this review will act as a road map to guide the new researchers towards the concept of nanofabrication that can be employed to develop Carbon Nanotube based platform for sensing applications.

Artificial skin devices are able to mimic the flexibility and sensory perception abilities of the skin. They have thus garnered attention in the biomedical field as potential skin replacements. This Review delves into issues pertaining to these skin‐deep devices. It first elaborates on the roles that these devices have to fulfill as skin replacements, and identify strategies that are used to achieve such functionality. Following which, a comparison is done between the current state of these skin‐deep devices and that of natural skin. Finally, an outlook on artificial skin devices is presented, which discusses how complementary technologies can create skin enhancements, and what challenges face such devices.
