Microfluidic and Capillary Electrophoresis Applications

Microfluidics is the science and engineering of manipulating tiny volumes of fluid—often just nanoliters or picoliters—through miniaturized channels and chambers, enabling chemical and biological analyses that once required full laboratories to be performed on a chip the size of a fingernail. By combining techniques like capillary electrophoresis, which separates molecules by how they move through an electric field, with materials such as poly(dimethylsiloxane) and fabrication methods including 3D printing, researchers can build devices that diagnose disease, sequence DNA, or screen drug candidates with far less sample, cost, and time than conventional methods. A central challenge is pushing these systems toward reliable point-of-care use in clinical and low-resource settings, where devices must be robust, inexpensive, and operable without specialized training. Active work is also extending the scale downward into nanofluidics, where fluid behavior becomes governed by surface forces and single-molecule interactions, opening questions about how to design and control systems at that regime with sufficient precision and throughput.
