Improving Particle Collection Efficiency of Sampling Wipes used for Trace Chemical Detection

Improvement of the particle collection efficiency of sampling wipes is desirable for optimizing the performance of many wipe-based chemical analysis techniques used for trace chemical screening applications. In this note,...

Mesoporous Silica Nanoparticles in Chemical Detection: From Small Species to Large Bio-Molecules

A recompilation of applications of mesoporous silica nanoparticles in sensing from the last five years is presented. Its high potential, especially as hybrid materials combined with organic or bio-molecules, is shown. Adding to the multiplying effect of loading high amounts of the transducer into the pores, the selectivity attained by the interaction of the analyte with the layer decorating the material is described. Examples of the different methodologies are presented.

EU-SENSE detection system in mass gathering evacuation

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).

Research frontiers of chemical detection and measurements

Over the past decade, the global research agenda focused on finding paths to the future development of chemistry. Chemical detection and measurement is an important and fundamental discipline of chemistry and it keeps playing a significant role in chemical research in the next 10–15 years. The goal of chemical detection is to overcome the state-of-art temporospatial resolution limit. Meanwhile, the application of modern chemical technology to serve human health is also highly concerned. We have summarized 10 aspects related to the field, including complex samples analysis, biomacromolecule structure and function, single-entity analysis, large-scale scientific instrument, rapid chemical and electron transfer processes, big data and artificial intelligence, bioimaging, in vivo real-time detection, biomolecule recognition and disease therapy, and public health screening. In this review, we outlined the history and the frontiers of chemical detection and measurements in enhancing the development of chemical sciences. Moreover, we also focused on the major challenges that should be solved in the future in which researchers should develop new techniques and analytical methods to drastically accelerate chemical sciences.
