Monodisperse crystalline Ag nanoparticles were synthesized using a hydrothermal approach with chestnut shell extract as both reducing agent and stabilizer. Characterization tests revealed that the synthesized nanoparticles were spherical Ag nanoparticles with a face-centered cubic crystal structure. The functionalized Ag nanoparticles modified by chestnut shell extract exhibited significant inhibitory effects on Escherichia coli, Staphylococcus aureus, and Candida albicans, making them efficient antimicrobial agents.
The chestnut shell is usually discarded as agricultural waste and the random deposition of it can cause environmental problems. In this study, monodisperse crystalline Ag nanoparticles (AgNPs) were synthesized by a hydrothermal approach, in which the chestnut shell extract served as both reducing agent and stabilizer. The synthesized Ag nanoparticles were characterized by ultraviolet-visible (UV) spectrophotometry, transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD) measurements. The TEM, XRD and XPS results revealed that the synthesized product was spherical Ag nanoparticles with a face-centered cubic crystal structure. The antimicrobial activity test indicated that the Ag nanoparticles modified by the chestnut shell extract had an obvious inhibitory effect on Escherichia coli, Staphylococcus aureus and Candida albicans. The measured MIC and MBC of functionalized chestnut-shell-extract AgNPs against E. coli, S. aureus and C. albicans is relatively low, which indicated that the present functionalized chestnut-shell-extract AgNPs are an efficient antimicrobial agent.
