  • SURFACE MODIFIED STRUCTURE FOR IMPROVING HEMOCOMPATIBILITY OF BIOMEDICAL METALLIC SUBSTRATES
    Publication number: 20190030208
    Abstract: The present invention relates to a surface modification method for improving the hemocompatibility of a biomedical metallic substrate, comprising: fixing a sulfur-containing and nitrogen-containing monolayer film on the surface of oxide layer of the biomedical metallic substrate by molecular self-assembly. The surface modification improves the hydrophilicity and hemocompatibility of the biomedical metallic substrate in contact with the blood, and ensures that the biomedical metallic substrate is non-toxic to the endothelial cells.
    Type: Application

  • SURFACE MODIFICATION METHOD AND STRUCTURE FOR IMPROVING HEMOCOMPATIBILITY OF BIOMEDICAL METALLIC SUBSTRATES
    Publication number: 20170065748
    Abstract: The present invention relates to a surface modification method for improving the hemocompatibility of biomedical metallic substrate, comprising: fixing a sulfur-containing monomolecular film on the surface of oxide layer of a biomedical metallic substrate by molecular self-assembly. The surface modification will improve the hydrophilicity and hemocompatibility of the biomedical metallic substrate in contact with the blood, and ensure that the biomedical metallic substrate is non-toxic to the endothelial cells.
