APPARATUS AND METHOD FOR SURFACE MODIFICATION OF BIOLOGICAL MATERIAL

摘要

Provided are an apparatus and method for surface modification of a biological material for improving the osteogenesis and symphysis performance of an artificial substitute such as an implant, an artificial joint or the like used in a biological material, and various parts used in the operation thereof. The apparatus for surface modification of a biological material according to the present invention comprises: a vacuum tank of which the inside is maintained to be vacuum; a magnetron vapor deposition source for generating plasma ions of a biological material, combined to the vacuum tank; a sample mounting table for mounting a sample, provided at the location facing the magnetron vapor deposition source inside the vacuum tank;a pulsed direct current power unit for supplying pulsed direct current power to the magnetron vapor deposition source so as to generate plasma ions of a biological material sputtered from the magnetron vapor deposition source; and a high voltage pulsed power unit for supplying a negative (-) high voltage pulse to the sample mounting table so as to carry out the ion injection of the plasma ions of a biological material formed from the magnetron vapor deposition source.
