Abstract: A protein functionalized anti-inflammatory nanoparticle and a method of preparing the protein functionalized anti-inflammatory nanoparticle is disclosed. The protein functionalized anti-inflammatory nanoparticle includes a central core comprising a hyaluronic acid coated chitosan nanoparticle and surface adsorbed anti-inflammatory proteins forming an outer shell around the central core, wherein the surface adsorbed anti-inflammatory protein is AGP (alpha-1-acid glycoprotein). The method of preparation includes dispersing chitosan nanoparticles in acetic acid/acetate buffer to produce a dispersion, adding an equal amount of acetate buffer containing hyaluronic acid under vigorous stirring to form hyaluronic coated chitosan nanoparticle (HA-CS) and functionalizing the hyaluronic coated chitosan nanoparticle with surface adsorbing anti-inflammatory protein AGP, to form the protein functionalized anti-inflammatory nanoparticle.
