Abstract:Osteoblast viability, proliferation, protein expression and mineralization were studied on bare, micro-and nanoporous silicon (Si) substrates. Micro-and nano-porous-Si substrates were prepared by anodic etching of silicon in ethanolic hydrofluoric acid and characterized using scanning electron and atomic force microscopies. Mouse osteoblasts were cultured on these substrates and cellular response to these surfaces was assessed using the Live/Dead Cell Viability assay and the MTT assay for cell proliferation.
