Design and fabrication of microfluidics devices for molecular biology applications

In the past decade, microfluidics has emerged as a rapidly growing area with potential to reduce cost and reagent consumption. It has been used for detection of nucleic acids and high-throughput screening of cells and metabolites. It is extensively used for extraction of DNA, RNA, proteins, biomolecules, as well as for cloning and transformation of plasmid into cells. Microfluidics is made up of polydimethylsiloxane (PDMS) polymer which is transparent and is used for preparation of a wide range of devices and systems. In this chapter, we discuss advances and challenges of using microfluidics in molecular biology and its biomedical applications.
