Nanoparticles for controlled release of anti-biofilm agents WO2014130994 (A1): a patent evaluation.

Nanoparticles based on poly(dimethylaminoethyl methacrylate)-b-poly(dimethylaminoethyl methacrylate-co-propylacrylic acid-co-butyl methacrylate) (p-DMAEMA-b-(DMAEMA-co-PAA-co-BMA)) were loaded with farnesol or apigenin for the controlled, pH-dependent release of the two agents to inhibit pathogenic bacteria-producing biofilms. The inventions are mainly directed against Streptococcus mutans, the oral cavity bacterium responsible for dental caries.
