The materials used for the fabrication of most microfluidic chips include glass, silicon, quartz, and plastics ( Materials Used in Microfluidic Devices) In addition to cost and optical, electric, and physical properties, careful consideration must be given to the surface chemistry of the material ( Surface Modification, Methods). In fact, surface chemistry plays a major role in chemical cytometry, as protein adsorption to the channel walls can degrade the separation performance and make the electroosmotic flow unreproducible. 

Poly(dimethylsiloxane) (PDMS) is probably the most popular material used in microfluidic devices at present. PDMS is a transparent elastomeric material that is made by heating a precursor mixture containing vinyl-terminated linear pol)miers of poly(dimethylsiloxane), a certain amount of a cross-linking agent, and a catalyst. The microfabrication of PDMS is rather straightforward and cost-effective by casting a liquid precursor mixture over a mold and heating at 60 - 80 °C for several hours, an elastomeric solid with a faithfully replicated microstructure can be formed. This process is often referred to as...
