BioMEMS using electrophoresis for the analysis of genetic mutations.

Biomedical microelectromechanical systems (BioMEMS) are rapidly emerging in many areas of genetic analysis. These devices demonstrate potential for rapid analysis using modular components capable of sample purification, amplification, mutation discrimination and detection on small, portable point-of-care instruments. Here, various approaches to genetic mutation detection and the modern analysis platform, capillary electrophoresis, will be briefly reviewed. Microfluidic devices will be discussed in relation to fabrication techniques, mutation detection using simple electrophoretic separations, multiplexed designs and modular functionalities, as well as challenges and issues surrounding this technology.
