METHODS FOR IMPROVING THE BIOACTIVITY CHARACTERISTICS OF A SURFACE AND OBJECTS WITH SURFACES IMPROVED THEREBY

摘要

A method for improving bioactivity of a surface of a surgical suture and sutures prepared thereby provides forming a gas-cluster ion-beam (GCIB) in a reduced-pressure chamber, introducing a surgical suture into the reduced-pressure chamber, and irradiating at least a first portion of the surface of said surgical suture with a GCIB derived beam.
