Plasma surface modification of poly(D,L-lactic acid) as a tool to enhance prote...
Alves, C. M.; Yang, Y.; Marton, D.; Carnes, D. L.; Ong, J. L.; Sylvia, V. L.; Dean, D. D.; Reis, R. L.; Agrawal, C. M.We have studied the influence of oxygen radio frequency glow discharge (RfGD) on the surface and bulk properties of poly(D,L-lactic acid) (PDLLA) and the effect of this surface modification on both protein adsorption and bone cell behavior. PDLLA films were characterized before and after plasma surface modification by water contact angle, surface energy, and adhesion tension of water as well as by scanning elec...
Modulating bone cells response onto starch-based biomaterials by surface plasma...
Alves, C. M.; Yang, Y.; Carnes, D. L.; Ong, J. L.; Sylvia, V. L.; Dean, D. D.; Agrawal, C. M.; Reis, R. L.The effect of oxygen-based radio frequency glow discharge (rfGD) on the surface of different starch-based biomaterials (SBB) and the influence of proteins adsorption on modulating bone–cells behavior was studied. Bovine serum albumin, fibronectin and vitronectin were used in single and complex protein systems. RfGD-treated surfaces showed to increase in hydrophilicity and surface energy when compared to non-mod...
