Designing of silver nanoparticles in gum arabic based semi-IPN hydrogel.

Semi-interpenetrating network (SISH-GA) composed of gum arabic and crosslinked copolymer of poly(2-hydroxyethyl methacrylate-co-acrylic acid) was synthesized in the presence of initiator ammonium persulfate (APS), crosslinker N,N'-methylene bis acrylamide (MBA), catalyzed by [CuSO4/glycine] chelate complex and finally loaded nanoparticle inside the networks via in situ reduction of silver nitrate (AgNO3) using trisodium citrate (Na3C6H5O7) as reducing agent. Characterization of the product was performed along with its degradability in Escherichia coli medium.
