Site specific oral delivery of many biopharmaceutical classification system (BCS) class II and IV drugs is challenging due to their poor solubility, low permeability and degradation in the gastrointestinal tract. Whilst colloidal carriers have been used to improve the bioavailability of such drugs, most nanocarriers based drug delivery systems suffer from multiple disadvantages, including low encapsulation efficiency (liposomes, polymeric nanoparticles), complex synthesis methods (silica, silicon-based materials) and poorly understood biodegradability (inorganic nanoparticles). Herein, a novel pH responsive nanocolloids were self-assembled using natural compounds such as bovine β-lactoglobul..
