Controlling the size and swellability of stimuli-responsive polyvinylpyrrolidone-poly(acrylic acid) nanogels synthesized by gamma radiation-induced template polymerization

► This study aims to develop a simple and efficient method for producing nanoscale sized gel particles by gamma radiation. ► Many parameters affecting the nanogel products were investigated in order to have a successful production of pH sensitive nanogel. ► Characterization of the PVP/PAAc nanogels is carried out, including morphological structure and equilibrium swelling studies.
