Microfluidic and Capillary Electrophoresis Applications

Microfluidics and capillary electrophoresis are concerned with manipulating tiny volumes of fluid—often just nanoliters or picoliters—through precisely engineered channels to perform chemical and biological analyses that once required a full laboratory bench. By integrating pumps, mixers, separation chambers, and detectors onto a single chip the size of a credit card, researchers can run diagnostic tests faster, cheaper, and with far less sample material than conventional methods allow. Much of the current work centers on finding fabrication approaches—such as 3D printing and soft lithography using poly(dimethylsiloxane)—that make these devices easier and cheaper to manufacture at scale, and on extending the technology into nanofluidic regimes where individual molecules can be detected and sorted. A central open question is how to move these systems reliably from controlled lab settings into point-of-care environments where power, temperature, and user expertise cannot be taken for granted.
