Electrophoretic sample stacking comprises a group of capillary electrophoretic techniques where trace analytes from the sample are concentrated into a short zone (stack). This paper is a continuation of our previous reviews on the topic and brings a survey of more than 120 papers published approximately since the second quarter of 2016 till the first quarter of 2018. It is organized according to the particular stacking principles and includes chapters on concentration adjustment (Kohlrausch) stacking, on stacking techniques based on pH changes, on stacking in electrokinetic chromatography and on other stacking techniques. Where available, explicit information is given about the procedure, electrolyte(s) used, detector employed and sensitivity reached. Not reviewed are papers on transient isotachophoresis which are covered by another review in this issue.

“…The developed Pd-GCME was then used to detect GSR. The nitrite from the gunshot was extracted as given by Erol et al's method (Erol et al, 2017). The result obtained gave a good linear range of 0.10μmol/L-4mmol/L with LOD at 0.030 μm.…”

Background Gunshot residue (GSR) is a shred of important trace evidence which helps forensic scientists solve a huge range of incidents related to firearms. The identification of the shooter to bullet identification from a gunshot wound help reconstruct a scene of the crime. Main body The review of this scientific paper is based on gunshot residue, its composition, and the growing advanced technology which allow us to study about how GSR analysis help to identify and detect residues. Various methods are acquired to identify and analyze organic and inorganic residues present when ammunition is fired. The review highlights the composition of GSR, its collection methods, and analysis part which emphasize on all the methods developed so far. The use of conventional methods including colorimetric and instrumentation-based analysis and advanced technology including electrochemical technique for detecting residues from the last 50 years. Spot tests or chemical tests were performed but they degrade the sample and can sometimes cause hindrance with some other nearby material present at the crime scene. Instrumentation techniques including AAS, ICP-MS, SEM, SEM-EDX, GC, HPLC, etc. are discussed in detail. Mostly advanced electrochemical methods developed are for inorganic gunshot residues (IGSR), but some researchers worked on both residues. Also, the fabricated electrochemical cells are replaced by a single strip-based technique for easy detection. So, to combat these issues, various scientists are moving towards sensor-based methods for rapid and reliable detection. These methods are more user-friendly, sensitive, and cost-effective and provide rapid detection results. Conclusions This review results in the composition of GSR, its collection methods, and analysis using sophisticated methods that emphasize all the methods developed so far and it also culminates the merits and demerits of all detection methods.

“…Explosion cases pose serious harm to people's lives and social order. As the most commonly used explosive, nitrous explosive will produce nitrite (NO 2 − ) after the explosion [1] . According to the Locard material exchange principle, the explosives or their residues left in the hands of criminals will be reflected in the latent fingerprints in explosion cases.…”

Nitrate (NO 2À ) is a common explosion residue, whose identification is conducive to the detection of explosion cases. Herein, the chemical reaction of o-phenylenediamine (OPD) with NO 2 À and the inclusion action of hydroxypropyl-β-cyclodextrin (HP-β-CD) are successfully used to visualize the latent fingerprint with attached NO 2 À . Furthermore, we have realized the semi-quantitative analysis of NO 2 À in latent fingerprints by processing the color information of fingerprint images digitally according to the HSV color space, which is constructing the data relationship between the hue (H), saturation (S), value (V), and NO 2 À of the fingerprint image. This method is fast, noninvasive, and convenient to operate. It realizes the simultaneous identification of the form of latent fingerprints. And its chemical composition(NO 2 À ) provides a reference for the rapid detection of explosive residues of ammonium nitrate explosive in latent fingerprints.
