Abstract
The invention provides for a method of improving bioactivity of a surface of an implantable object. The invention also provides for a method of improving bioactivity of a surface of biological laboratory ware. The invention further provides a method of attaching cells to an object. The invention even further provides for a method of preparing an object for medical implantation. The invention also provides for an article with attached cell, and for an article for medical implantation. Improvements result from the application of gas-cluster ion beam technology and from the application of neutral beam technology, wherein neutral beams are derived from accelerated gas-cluster ion beams.
