Green synthesis of silver nanoparticles (Ag) using Dracaena Sanderiana’s leaves extract and its structural, morphological, and antimicrobial study

Abstract Silver (Ag) nanoparticles are one of the most studied and advanced functional materials. They are the potential candidates in almost every field of life. The useful properties are enhanced in various applications like sensors, catalysis, and antibacterial activity. The method of synthesis has a significant effect on the size and shape of silver nanoparticles. The green synthesis of silver nanoparticles using natural products has been an excellent solution for chemically derived silver nanoparticles. Herein, a rapid, process has been established using an extract from leaves of Dracaena Sanderiana (Lucky bamboo) plant, for the synthesis of metallic silver nanoparticles (Ag NP) for the first time. The synthesized Ag nanoparticles were characterized by X-ray diffraction (XRD), UV-visible spectroscopy, Fourier transform infrared spectroscopy (FTIR), and transmission electron microscopy (TEM). The agar cup diffusion method was used to check the antimicrobial effect of Ag NPs on different microorganisms with a zone of inhibition of 21 mm for gram-positive Staphylococcus aureus and 18 mm for gram-negative E. coli when 50 µg of Ag NPs were used. Thus, the silver nanoparticles are excellent antimicrobial agent.
