  • Synthesis of biocompatible nanocomposite hydrogels as a local drug delivery system
    Publication number: 20070212419
    Abstract: Nanocomposite biocompatible hydrogels (NCHGs) may be synthesised as model systems for in situ cured local drug delivery devices for treatment of inter alia periodontal infections. The composite includes the following components: nanoparticles (NPs), a matrix gel, and chlorhexidine (CHX) or other antibacterial drug. The NPs were obtained by free radical initiated copolymerization of the monomers, 2-hydroxyethyl methacrylate (HEMA) and polyethyleneglycol dimethacrylate (PEGDMA), in aqueous solution. The same monomers were used to prepare crosslinked matrices by photopolymerization. NCHGs were obtained by mixing NPs, monomers, and drug in an aqueous solution then crosslinked by photopolymerization.
