The detection and identification of materials from a distance is highly desirable for applications where accessibility is limited or there are safety concerns. Raman spectroscopy can be performed remotely and provides a very high level of confidence in detection of chemicals through vibrational modes. However, the remote Raman detection of chemicals is challenging because of the very weak nature of Raman signals. Using a remote Raman system, we performed fast remote detection of various solid and liquid chemicals from 1752 m during afternoon hours on a sunny day in Hawaii. Remote Raman systems with kilometer target range could be useful for chemical detection of volcanic gases, methane clathrate icebergs or fire ice, toxic gas clouds and toxic waste, explosives, and hazardous chemicals. With this successful test, we demonstrate the feasibility of developing future mid-size remote Raman systems suitable for long range chemical detection using helicopters and light airplanes.

Current CBRNe detection systems are mainly available as standalone detectors, and seldom offer the potential of networking and data fusion. The research objective is to simulate the scenario-based models built in a virtual environment to examine the possible impact of the EU-SENSE system on chemical detection technology, based on an innovative CBRNe detection and identification system, which is a network of heterogeneous sensor nodes, on the evacuation of a mass gathering. The chemical detection system presents real possibilities of understanding situations that depend on the first symptoms of human health and behaviour. This information will facilitate taking appropriate measures when CBRNe hazard forces to evacuation, including quick identification of the hazard and necessity to modify preliminary evacuation gates (in terms of their localization and width).

There is a variety of methods available for the rapid detection and identification of viruses by electron microscopy as described in several reviews. The predominant techniques are classified as direct electron microscopy (DEM), immune electron microscopy (IEM), liquid phase immune electron microscopy (LPIEM) and solid phase immune electron microscopy (SPIEM). Each technique has inherent strengths and weaknesses. However, in recent years, the most progress for identifying viruses has been realized by the utilization of SPIEM.
