Abstract
A water-based and surfactant-free microwave synthesis of polymer nanoparticles includes the entrapment of diisopropyl fluorophosphatase (DFPase) within poly(4-vinylpyridine) (PVP) nanoparticles. The resulting nanoparticles are approximately 80-100 nm in diameter and reactive activity of DFPase is maintained after encapsulation.
