Claim Text:
1. An artificial tissue comprising living cells attached to a porous tissue engineering scaffold comprising a porous polymer having a conformal aluminum oxide coating, a titanium oxide coating, or both an aluminum oxide and a titanium oxide coating adherent to the surface of the porous polymer, wherein the porous polymer is a nonabsorbable polymer selected from a polyethylene polymer, a polyethylene copolymers, a styrene homopolymer, a styrene copolymer, a polyurethane, a polypropylene homopolymer, a propylene copolymer, a polyamide, a polyalkyleneterephthalate, a polyvinylidene fluoride, a polycarbonate, a polymer of an acrylate ester, a polymer of a methacrylate ester, a polyether, and polytetrafluoroethylene, and wherein the coating has a thickness of from about 1 to 20 nanometers and covers at least 95% of the external surface of the porous polymer and internal surfaces of the pores.
