Abstract

See full text

The invention provide for a method of improving bioactivity of a surface of an object. The invention further provides for a method of preparing an object for medical implantation. The invention even further provide for an article made by a method comprising the steps of forming a gas-cluster ion-beam in a reduced-pressure chamber, introducing the article into the reduced-pressure chamber, and irradiating at least a portion of the surface of the object with the gas-cluster ion-beam. The invention still further provides for an article for medical or surgical implantation made by a method comprising selecting at least a portion of a surface of the object for increased bioactivity, forming a gas-cluster ion-beam in a reduced-pressure chamber, introducing the object into the reduced-pressure chamber, and irradiating the selected at least a portion with the gas-cluster ion-beam to increase the bioactivity of the at least a portion.
