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
