Abstract: The various embodiments of the present disclosure relate generally to the modification of biomaterials with microgel films. More particularly, the various embodiments of the present invention are directed to the modification of biomaterials and medical devices with microgel thin films to alter a host's response to an implanted biomaterial or medical device. An embodiment of the present invention comprises a coated biomaterial comprising a non-fouling polymer film attached to at least a portion of a surface of the biomaterial, the non-fouling polymer film comprising a plurality of a cross-linked polymer microparticles, wherein at least a portion of the cross-linked polymer microparticles are covalently bonded to at least a portion of the surface of the biomaterial.

Abstract: An embodiment of the present invention may take the form of a system that may use the heat removed from an exhaust stream during an exhaust gas recirculation process to heat the fuel consumed by a turbomachine.

Abstract: Methods and compositions are provided for improving tissue growth and device integration in vivo. Substrates and devices coated with an ?2?1 or ?5?1 integrin-specific ligand are provided. The substrates and devices coated with an ?2?1 or ?5?1 integrin-specific ligand are shown to have greater tissue formation on the surface relative to controls, in particular greater bone formation.

Abstract: Non-crystalline, porous bioactive glass and ceramic materials are prepared that permit in vitro formation of bone tissue when exposed to a tissue culture medium and inoculated with cells. The bioactive glass and ceramic materials are treated such that when used in contact with anchorage-dependent cells, there is enhanced cell attachment and cell function to provide expeditious tissue growth in vitro or in vivo. Treatment involves immersing the glass or ceramic material in an aqueous solution containing ions in a concentration typical of interstitial fluid followed by immersion in an aqueous solution containing at least one cell adhesion molecule. Immersion may also be in an additional aqueous solution containing an additional cell adhesion molecule before or after immersing in the solution containing ions. The glass material is preferably formed from SiO2, CaO, Na2O and P2O5.
