Significant progress has been made in the field of analytical chemistry in the development of microchip electrophoretic separation systems for pharmaceutical and biological analysis in recent years. These cutting-edge platforms provide scientists and medical professionals with strong instruments for accurately and efficiently analyzing complicated biological samples and pharmaceutical substances. A scaled-down variant of conventional electrophoresis called microchip electrophoresis has completely changed how we handle analytical problems in the pharmaceutical and biological sciences [1, 2].

Employing an electric field to move molecules or particles within a microfluidic device. These devices are usually etched or micro machined to generate micro channels for sample manipulation. They can be composed of glass, silicon, or polymers. Like classical electrophoresis, microchip electrophoresis operates on the same basic principle: charged molecules migrate across a medium in response to an electric field, and the size and charge of the molecules control how quickly they migrate. On the other hand, the system's downsizing offers a number of benefits, including as improved separation efficiency, lower sample and reagent usage, quicker analysis times, and portability [3, 4].

The microchip, which forms the core of the system, has the electrodes, reservoirs, and micro channels required for sample loading, separation, and detection. Through an inlet or reservoir, the sample is injected into the microchip; capillary or electro kinetic injection techniques are frequently used. Depending on the analytes and the objectives of the separation, a variety of electrophoresis techniques can be used, such as micellar electro kinetic chromatography (MEKC), capillary zone electrophoresis (CZE), and capillary isoelectric focusing (CIEF). Real-time analysis is facilitated by the integration of detection techniques like conductivity, UV-Vis absorption, and fluorescence within the microchip [5, 6].

DNA sequencing is frequently carried out using microchip electrophoresis, which enables high-throughput examination of DNA fragments at a remarkable speed and resolution. Microchip electrophoresis is a technique used by researchers to separate and measure proteins in biological materials. Understanding post-translational changes and protein expression is particularly helpful in proteomics investigations. Individual cell analysis is made possible by microchip electrophoresis, which provides insights into the heterogeneity and function of cells. This technology is essential for early diagnosis and tailored medication since it can detect and measure biomarkers linked too many diseases [7, 8].

By evaluating medicinal compounds, their impurities, and stability, microchip electrophoresis helps to expedite the processes involved in drug development. Pharmaceutical products are subjected to quality control using this technology to make sure they adhere to regulatory requirements. It is used to research the distribution, metabolism, and effectiveness of medications by examining their pharmacokinetics and pharmacodynamics. Microchip electrophoresis is a tool used by researchers to examine drug compositions and find possible interactions between excipients and active components [9, 10].


Systems for microchip electrophoretic separation have become a highly effective and adaptable instrument for pharmaceutical and biological analysis. The speed and precision with which they can separate molecules and particles has revolutionized the way scientists and medical professionals tackle challenging analytical problems. Microchip electrophoresis is positioned to play a significant role in advancing our understanding of biological systems and enhancing pharmaceutical research and development because to continuous technological and methodological developments.
