Abstract

Silver nanoparticles (AgNP's) possess inherent biological potentials that have obliged an alternative, eco-friendly, sustainable approach to "Green Synthesis." In the present study, we synthesized Green Silver Nanoparticles (GAgNP's) using Curcuma longa L. (C. longa) flower extract as a reducing and capping agent. The synthesized GAgNP's were characterized using UV-Visible spectroscopy, X-ray diffraction (XRD), and High-resolution transmission electron microscopy (HR-TEM), which confirmed their homogeneity and physical characteristics. The GAgNP's were found to contain crystalline silver through XRD, and the particles were confirmed to be homogeneous and spherical with a size of approximately 5 nm, as evidenced by UV-Visible spectroscopy, XRD, and HR-TEM. In addition, the biological potential of GAgNP's was evaluated for their antibacterial activities. GAgNP's showed significant activity and formed different sizes of inhibition zones against all selected bacteria: Mycobacterium smegmatis (M. smegmatis) (26 mm), Mycobacterium phlei (M. phlei), and Staphylococcus aureus (S. aureus) (22 mm), Staphylococcus epidermidis (S. epidermidis) and Klebsiella pneumoniae (K. pneumoniae) (18 mm), and Escherichia coli (E. coli) (13 mm). The MIC value of GAgNP's was found to be between 625 ug/mL-39.06 ug/mL for different microbes tested. With further research, the green synthesis of GAgNP's using C. longa flower extracts could lead to the development of effective antibacterial treatments in the medical field.
