1. A method for forming a bacteria-repelling and blood-compatible modified surface on a substrate, comprising the sequential steps of:

  • a. activating the surface of a substrate;

    b. grafting the resulting activated surface of the substrate with a hydrophilic monomer, andc. subjecting the resulting grafted substrate to an SO2 plasma treatment,whereby bacterial adhesion and blood platelet adhesion to said modified surface after exposure to said plasma treatment is less than prior to said plasma treatment.
