Patent ID: 8778378

Claim:
A bioactive antibacterial composite comprising a biocompatible polymer, a porous calcium phosphate and a bioactive glass, wherein the bioactive glass consists of: (a) particles having a particle size of less than about 53 microns (μm) and (b) particles having a particle size range from about 90 microns (μm) to about 150 microns (μm), wherein the biocompatible polymer is present in an amount from about 10% to about 20% by weight of the composite, the calcium phosphate is present in an amount from about 50% to about 75% by weight of the composite and the bioactive glass is present in an amount from about 10% to about 35% by weight of the composite, and wherein the bioactive antibacterial composite has antibacterial efficacy of greater than about 3.7 log reduction at 1 day when tested based on USP <51> standard at a bioactive glass concentration of between about 50 to about 200 mg/mL.
