“…[28,29] Finally, other studies have been carried out for the determination of intact pre-blast nitrostarch and nitrocellulose, a secondary explosive that may be present in some explosives of interest such as dynamites or home-made explosives. [30,[32][33][34][35] CE is a promising candidate for the analysis of cations and anions due to its ability to detect charged macromolecules at low concentrations, and thus can be used for collection post-blast residues at crime scene. However, matrix effects and contamination must be considered due to the prevalence of anions and cations in the environment.…”

“…With the method developed, amounts in the order of 250–400 pg of nitrocellulose were detected. Figure B shows an average electropherogram of one sample of dynamite analyzed under the optimized conditions, as well as the standard deviation relative to the intensity of each peak from the polymeric profile .…”

This paper provides an up-to-date overview on the use of microstructured optical fibers (MOFs) in chemical sensing during the last ten years, more specifically, applications in liquid media including the use of solid-core photonic crystal fibers, hollow-core PCFs and other MOFs and related microstructures. To this aim, a classification of different types of fiber-based chemical sensors is first made, followed by a description of the most important MOFs and their operation principles in chemical sensing. Then, studies on the use of MOFs in fluorescence, Raman and SERS detection among other detection principles are discussed. Finally, literature including the implementation of these microstructures in homemade and commercial analytical equipment is summarized. This review intends not only to give a current perspective on the use of MOFs and microstructures in chemical sensing, but also to make an approach between the fields of optical fiber and analytical chemistry, in order to understand the basic principles of operation in this promising frontier of knowledge.

Derivatisation is an integrated part of many analytical workflows to enable separation and detection of the analytes. In CE, derivatisation is adapted in the four modes of pre-capillary, in-line, in-capillary, and post-capillary derivatisation. In this review, we discuss the progress in derivatisation from February 2015 to May 2017 from multiple points of view including sections about the derivatisation modes, derivatisation to improve the analyte separation and analyte detection. The advancements in derivatisation procedures, novel reagents, and applications are covered. A table summarising the 46 reviewed articles with information about analyte, sample, derivatisation route, CE method and method sensitivity is provided.
