This work reports the preparation of silver nanoparticles (AgNPs) and synthesis of natural based hydrogel scaffold with an inclusion of AgNPs, chitosan/alginate/silver nanoparticles. The synthesised hydrogel scaffolds were characterised by using Fourier Transform Infrared Resonance Spectroscopy (FTIR). The FTIR result revealed that the shifting of the three peaks of 3252.95 cm−1 (–OH and –NH2 stretching), 1591.33 cm−1 (C=O stretching) and 1411.88 cm−1 (N–H stretching) of chitosan/alginate/silver nanoparticles in compared to chitosan/alginate hydrogel indicating the presence of electrostatic interaction of –NH3+ in chitosan reacted with the – COO– group of alginate and binding of the silver (Ag). These results indicated that chitosan/alginate/silver nanoparticles were consolidated in the composite system.
