This invention relates, e.g., to a composition suitable for administration to the central nervous system (CNS), comprising a block copolypeptide hydrogel, which comprises a biologically active material that is mixed with the hydrogel or that is attached to the polypeptide chain of the hydrogel, wherein the composition is suitable for administration to the CNS. Also disclosed are methods of making and using compositions of the invention as depots or as scaffolds for cell migration, and pharmaceutical compositions and kits for implementing methods of the invention.
Bioactive molecules have been coated on nanotubular structured titanium substrates by molecular plasma deposition. The coatings promote cell adhesion and are particularly suited for orthopedic implants that provide improved bone cell adhesion and new tissue growth. Nanodimensional features on titanium substrates are engineered using electrochemical anodization techniques. The nanostructured surfaces provide superior support for a wide selection of polypeptide coatings.
