Abstract
A method for immobilization of heparin on polymeric material is disclosed, said method comprising selecting a substrate made from a polymeric material, pre-treating said substrate, mounting said substrate into a vacuum chamber, evacuating the vacuum chamber to pressure essentially below 100 Pa, preferably below 1 Pa, selecting a source of NH2 radicals, leaking the NH2 radicals from said source into said vacuum chamber during continuous pumping of said vacuum chamber, interacting said NH2 (NH 2 ) radicals with said substrate made from a polymeric material, evacuating said vacuum chamber, venting said vacuum chamber to atmospheric pressure, and covalent bonding of activated heparin on said substrate.
