DescriptionThis protocol details the fabrication of a 2 layer PDMS device, consisting of a valve layer (top) and channel layer (below). It is assumed that masters for respective layers have already been fabricated (see Godin:Protocols/SU-8 Master, Godin:Protocols/AZ Master). The idea is to modify the silicone elastomer base to curing agent ratio, thereby modifying PDMS elasticity. Valve Layer
