摘要: A method for enhancing bio-material capability for use as a supporting surface for cell culture is disclosed. The method requires exposure of the bio-material to a plasma polymerizable polymer gas, which includes oxygen-containing organic molecules. The material surfaces are then subjected to an RF plasma gas discharge in the presence of the gas, causing a deposition on the exposed material surfaces of a conformal overcoating of the polymer on the material. The deposition enhances fibronectin adsorption and hence cell attachment, spreading and cell growth. Preferred polymerizable gases are acetone, methanol, and ethylene oxide.
