Motivation and features for Microfluidic and Lab-on-a-chip
Lab-on-a-chip is the main platform of Microfluidic technology. The computer chips miniaturize the size of computer, Lab-on-a-chip miniaturize the size of laboratory. In the past, chemists required a long period of time and a large amount of sample or reagent to complete the analysis or synthesis. However, using a square centimeter size chip instead of those large analysis instrument not only reduces the consumption of resource but also shortens the experimental time. In addition, because of these miniatures, the sewage emissions are also reduced. In other words, it is a kind of green technology.
With the research and development of microfluidic chips, it has many unique characteristic features. First, the chip material becomes diversified from those expensive glass and silicon materials to PDMS (polydimethylsiloxane), PMMA (poly methyl methacrylate), PC (polycarbonate) and other polymer materials allows a high degree of flexibility, while the cost are continually decreasing [2]. Second, the manufacturing processes are more precision by using automatic and numerical controlled sub-UV laser to produce a smooth microchannel instead of hand based MEMS (microelectromechanical) [3]. Third, the components are highly integrated in a small chip including pumps, valves, channels, reactors, etc. [3]. The fourth point is the precision drive technology mainly using fluid power,
