“…However, the results demonstrate good poten-tial for applying the proposed feature representations for e-nose applications. Rezende et al (2022) reported using portable analytical platforms combined with chemometrics to discriminate between 45 adulterated and 5 authentic whiskey samples. A microchip electrophoresis system with an integrated contactless conductivity detector was used to obtain anionic whiskey profiles.…”

In order to safeguard authentic whiskey products from fraudulent or counterfeit practices, high throughput solutions that provide robust, rapid, and reliable solutions are required. The implementation of some analytical strategies is quite challenging or costly in routine analysis. Qualitative screening of whiskey products has been explored, but due to the nonspecificity of the chemical compounds, a more quantitative confirmatory technique is required to validate the result of the whiskey analysis. Hence, combining analytical and chemometric methods has been fundamental in whiskey sample differentiation and classification. A comprehensive update on the most relevant and current analytical techniques, including spectroscopic, chromatographic, and novel technologies employed within the last 5 years in whiskey analysis for authentication, discrimination, and quality control, are presented. Furthermore, the technical challenges in employing these analytical techniques, future trends, and perspectives are emphasized.

“…Moreover, its applications extend to forensic sciences because of the rapid screening and on‐site monitoring properties of the integrated ME systems that enable its use in crime scene investigations [65, 66]. Such applications involve forensic genotyping [66, 67], analysis of illicit drugs [68], separation of explosive residues [69], and forensic screening of adulterations in beverages [70–72]. It was also applied to the analysis of small molecules such as pharmaceutical compounds [73–78], amino acids [75, 79, 80], environmental contaminants [81–83], and specific biomarkers [84–87].…”

Life‐threatening diseases, such as hepatitis B, pneumonia, tuberculosis, and COVID‐19, are widespread due to pathogenic bacteria and viruses. Therefore, the development of highly sensitive, rapid, portable, cost‐effective, and selective methods for the analysis of such microorganisms is a great challenge. Microchip electrophoresis (ME) has been widely used in recent years for the analysis of bacterial and viral pathogens in biological and environmental samples owing to its portability, simplicity, cost‐effectiveness, and rapid analysis. However, microbial enrichment and purification are critical steps for accurate and sensitive analysis of pathogenic bacteria and viruses in complex matrices. Therefore, we first discussed the advances in the sample preparation technologies associated with the accurate analysis of such microorganisms, especially the on‐chip microfluidic‐based sample preparations such as dielectrophoresis and microfluidic membrane filtration. Thereafter, we focused on the recent advances in the lab‐on‐a‐chip electrophoretic analysis of pathogenic bacteria and viruses in different complex matrices. As the microbial analysis is mainly based on the analysis of nucleic acid of the microorganism, the integration of nucleic acid‐based amplification techniques such as polymerase chain reaction (PCR), quantitative PCR, and multiplex PCR with ME will result in an accurate and sensitive analysis of microbial pathogens. Such analyses are very important for the point‐of‐care diagnosis of various infectious diseases.
