Facile Approach for the Development of Burly Starch- Silver Hydrogel Nanocomposites for Antimicrobial Applications

Abstract:

This paper presents the development of silver nanoparticles entrapped starch-polyacrylic acid hydrogel by a one step facile strategy. Formation of silver nanoparticles was confirmed by TEM and SPRE. Hydrogen bond interaction present in the hydrogel network was manifested from the FTIR spectroscopy. Silver nanoparticles in the face centred cubic lattice were confirmed by XRD. Visco-elastic properties studied by rheological analysis showed storage modulus of ~1500 Pa and exhibited a high storage modulus than loss modulus revealing the formation of strong gels. Phase transition temperature was confirmed by DSC. Antimicrobial screening studies of these hybrid gel exhibited antimicrobial activity to E.coli and S.aureus suggesting its applications for gram + ve and gram - ve bacteria.
