Patent ID: 8580291

Claim:
A bioactive, biodegradable, resorbable fibrous composite of bioactive, gel-like silica or metal oxide materials and biodegradable polymers, the fibrous composite comprising: a plurality of fibers, comprising not less than 25% hollow-core fibers, assembled into a sizable fibrous preform comprising pores in a conductive interconnecting-porous configuration, wherein (i) nanopores ranging in size from 1.5 to 10 nm in diameter are in and on the interconnected fibers and inner cores of the hollow fibers; and wherein the resulting fibrous composite has an overall surface area of greater than 1000 m 2 /g; and (ii) mesopores and macropores are interspaced between and among the interconnecting fibers of the porous configuration, wherein interfiber pore size ranges from 0.5 to 10 times fiber diameter providing fluid transport in <10 minutes.
