Controlling Protein Adsorption and Bone Cells Response to PDLLA by a Gas Plasma Surface Treatment

摘要

Oxygen-based RFGD treatment was shown to modify the surface of PDLLA films. Treated surfaces resulted more hydrophilic, presenting higher surface energy, as well as by chemical and morphology different. PDLLA properties achieved by means of surface modification promoted, in turn albumin and fibronectin adsorption. Although cell adhesion was unaffected by the surface treatment itself, higher cell densities were observed when combining gas plasma modification with the different protein systems.
