SARFUS: Application to PDMS oligomer Sarfus is used for the investigation of surface diffusion of polydimethylsiloxane (PDMS), a very useful material in many scientific and technological areas. For example, PDMS is used to transfer patterns in soft-lithography (microcontact printing) or as a substrate for microfluidics and stretchable electronics. Due to incomplete curing, oligomers can diffuse on a surface and great care has to be taken not to contaminate biological species in microfluidics channels, for example. [...]
