As the native poly(dimethylsiloxane)(PDMS)is unfavorable for cell adhesion and easy to adsorb proteins,the PDMS should be modified for cell-culture applications. In this study,the effectiveness of four simple PDMS surface modification methods for cell culture has been compared with the adhesion of MG-63 cells and the amount of bovine serum albumin(BSA)adsorption as indicators. The relationship between PDMS' surface wettability and topography and the MG-63 adhesion/BSA adsorption was studied. Four groups of ...
