    摘要: Uniform, functional polymer patches can be attached to a fraction of the surface area of living individual cells. These surface-modified cells remain viable after attachment of the functional patch. The patch does not completely occlude the cellular surface from the surrounding environment. Functional payloads carried by the patch may include, for example, drugs or other small molecules, peptides, proteins, thermally responsive polymers, and nanoparticles, or any other material that can be incorporated in a polymer patch of subcellular dimensions. The patch can include one or more polyelectrolyte multilayers (PEMs).

    摘要: One aspect of the present invention relates to an implantable medical device comprising a surface coated with a polyelectrolyte multilayer, wherein said surface is glass, metal, plastic, polymer, or fiberglass. Another aspect of the present invention involves a method of preparing a PEM-coated implantable medical device, comprising the step of applying a film to a surface of an implantable medical device, wherein said film comprises a polyelectrolyte multilayer and said surface is glass, metal, plastic, polymer, or fiberglass. Another aspect of the present invention involves a method of reducing the wear between two contacting materials, comprising the step of moving a first material in contact with a second material in an environment, wherein a first surface of said first material is in contact with a second surface of said second material, wherein said first surface, said second surface, or both is coated with a polyelectrolyte multilayer, thereby decreasing the wear of said first material, said second material, or both compared to the wear in the absence of said polyelectrolyte multilayer.
