Explain some of the defining characteristics of a microfluidic system. 2. In microfluidics gases and liquids share some of their behaviour properties describe at least four of them. Give an indication of the way in which they help or hinder microfluidic systems. 3. Name and describe briefly the main dimensionless parameters used in the field of microfluidics. 5. Outline and describe in your own words four intrinsic positive characteristics of microfluidicdevices. 6. Explain with diagrams if necessary six ways in which some of fundamental laws of physics are advantageous in the development of microfluidic devices. 4. What is a "Lab on achip" type device? Ensure a diagram is provided.
