Microfluidic channel device, soft lithography materials

The use of polymeric materials in microchips has gained popularity, especially in the fabrication of low-cost, disposable devices [3], It is particularly common to prototype polydimethylsiloxane (PDMS) chips, which can easily be fabricated using the soft lithography technique. This fabrication strategy is considered as a low-expertise route of microscale prototyping. It facilitates creation of micropatterns on a surface or within a microfluidic channel without the need for using photochemical processes [9]. Fabrication...
