Novel amphiphilic protein-loaded hyperbranched poly (amine-ester) copolymers nanoparticles were fabricated by double emulsion (DE) and nanoprecipitation (NP) methods. Encapsulation efficiency (EE) of nanoparticles to Bovine serum albumin (BSA) could reach 97.8% at BSA (0.01g/ml), internal phase volume (0.5ml), copolymer weight (50mg), and PVA concentration (4%, w/v) condition.
