Abstract

This study aimed to investigate the effect of pH on the green synthesis of silver nanoparticles using Blumea lacera (Bl) leaf extract and their anti-inflammatory properties. TEM analysis showed that the synthesized materials had a spherical shape and particle sizes began to decrease from 28 nm to 16 nm as the pH increased from 8.0 to 11.0. AgNPs synthesized at pH 11 exhibited higher anti-inflammatory activity (∼92% inhibition) when compared with synthesized AgNPs at pH 8.0–10.0 (86–47% inhibition). A proposed mechanism for AgNPs formation under alkaline medium was also presented.

利用具有增强抗炎活性的蓝草叶提取物进行ph驱动的纳米银生物合成

本研究旨在研究pH值对蓝草叶提取物绿色合成纳米银的影响及其抗炎作用。TEM分析表明，随着pH值从8.0增加到11.0，合成的材料呈球形，粒径从28 nm减小到16 nm。与pH 8.0-10.0合成的AgNPs相比，在pH 11下合成的AgNPs表现出更高的抗炎活性（抑制率为92%）（抑制率为86-47%）。提出了碱性介质下AgNPs的形成机理。
