  • LOCAL DELIVERY OF DRUGS FROM SELF ASSEMBLED COATINGS
    Publication number: 20220040385
    Abstract: The invention relates to oligofluorinated coatings and their use in drag delivery. The oligofluorinated coatings are compositions comprising formula (XVII). These coatings are used in a method of delivering a biologically active agent to a tissue surface in a mammalian tissue. This method occurs by contacting the surface with the coating including an oligofluorinated oligomer and a biologically active agent wherein the coating resides on the tissue surface and release the biologically active agent to the tissue surface.
