The photoresist SU-8 is a common material for the fabrication of polymer microfluidic systems. This leads to the question, how cells respond to SU-8 as a substrate. Here, we investigate the effects of oxygen plasma activated SU-8 on cell culturing by means of cell proliferation assays performed on SU-8 coated glass chips. The assays revealed an increase in cell proliferation on activated SU-8 surfaces as compared to untreated SU-8 surfaces. We conclude that the observed increase in proliferation is most likely caused by a change in the surface chemistry. (C) 2008 Elsevier B.V. All rights reserved.
