Abstract
A simple method to introduce microstructures to the surface of elastomeric materials such as silicone elastomers is described. The patterns are generated by forming microdroplets of a protective polymer onto a silicone elastomer film, hardening the polymer, and then removing the uncoated material by chemical etching. Cell attachment study results show that the treated material has a significantly enhanced biocompatibility compared to a non-treated control.
