Poly(N-vinylpyrrolidone)-grafted-acrylic acid biocompatible nanogels(NGs)were prepared using an exiting industrial type electron accelerator and setups,starting from semi-dilute aqueous solutions of acommercial PVP and the acrylic acid monomer. As a result, NGs witht unable size and structure can beobtained quantitatively. Sterility was also imparted at the integrated dose absorbed.The chemicalstructure of the NGs produced was confirmed through Fourier Transformer Infrared Spectroscopy(FT-IR).The molecular and physico-chemical properties of NGs,such as the hydrodynamic dimensions andsurface charge densities,for various polymer and monomer concentrations in the irradiated solutions,are discussed here.
