Green synthesis, Silver nanoparticles, Chitosan, Biopolymer


In this work, the silver nanoparticles (AgNPs) were successfully synthesized using chitosan derived
from shrimp shells through a simple and eco-friendly method called the green synthesis. The chitosan not only
acted as the reducing agent for Ag+, but also stabilized the AgNPs to protect nanoparticles from aggregation. The
as-synthesized colloidal chitosan-AgNPs was yellowish-brown color with a maximum absorption wavelength at
approximately 434 nm. The size and shape, and crystal structure of AgNPs were characterized by transmission
electron microscopy and X-ray diffraction spectrometry, respectively. The results indicated that the AgNPs was
spherical particles with a diameter of 23.5 ± 0.6 nm. The XRD pattern peaked at different diffraction angles
corresponding to the (111), (200), (220), and (311) planes indicated that AgNPs had face-centered cubic (fcc)
