Overview
Microfluidics enables conducting of biological andchemical experiments in very small volumes offluids. In basic and applied research, the volumesused in experiments usually range from 1 litre to1 microlitre. Microfluidic devices allow automating, controlling, and performing tests using evensmaller volumes. Manufacturing of microfluidicdevices is multidisciplinary, including the fieldsof mechanics, IT, engineering, material science,chemistry, and many others.
