Abstract
We report a simple method for controlled formation of highly-ordered, wrinkled diamond-like carbon (DLC) film on grooved poly(dimethylsiloxane) (PDMS) specimens. Grooved surfaces of the specimens were treated with Ar plasma prior to DLC coating, which resulted in the formation of wrinkled DLC film aligning perpendicular to the steps of the ridges. The wavelength and the amplitude of the resulting wrinkled film exhibited variation in the submicron- to micron-scale range according to the duration of Ar plasma treatment. Since surface topography at the microscale-to-nanoscale level affects cell function in almost all types of mammalian cells, the wrinkled, grooved surfaces coated with DLC film would be applicable to biomedical engineering fields.
