Fabrication of Polydimethylsiloxane Microfluidics Using SU-8 Molds

We detail the widely prevalent technique of polydimethylsiloxane (PDMS) molding using SU-8 for creating microfluidic chambers and channels. Although other techniques such as injection molding are more apt for mass manufacturing and cost-effective, PDMS molding is used almost exclusively for rapid prototyping in corporate and research environments because of its simplicity and fast turnaround time.
