Abstract:
1. A process for preparing an antimicrobial inorganic substrate, said process comprising coupling a functional group with an antimicrobial property onto a surface of said substrate in one or more steps by means of an organophosphorus coupling agent, wherein: the substrate is selected from the group consisting of metals, metal oxides, metal hydroxides, metal carbonates and metal phosphates; the organophosphorus coupling agent is selected from the group consisting of phosphonic acids and phosphonates of formula RPO(OX) (a) a group that is capable of releasing antimicrobial nitrogen monoxide; (b) a group which, after modification, has an intrinsic antimicrobial property or is capable of releasing species with antimicrobial properties, said group being selected from the group consisting of —(CH wherein the group is modified by immersion in a solution of silver nanoparticles or in a solution of AgNO 3 ; and (c) a group which is selected from —(CH
