摘要：
Ag nanoparticles (Ag NPs) with antibacterial properties were synthesized by using a one-step method. The reagents used were environmentally friendly, and no subsequent purification treatment was required. This method conformed to the concept of green chemistry, and the synthesized silver nanoparticles had biosafety and antibacterial properties. The structure of Ag NPs was investigated and characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and transmission electron microscopy (TEM). The particle size of Ag NPs was approximately 14.01 nm, and the particle size distribution was relatively uniform. The antibacterial properties of Ag NPs were studied by conducting an inhibition circle experiment and investigating the growth curve. Lignin-capped Ag NPs (L-Ag NPs) were synthesized and characterized as inorganic antibacterial agents with good antibacterial activity and no biological toxicity.
