The present investigation was done to explore the potential of Lantana camara (L. camara) flower in the fabrication of gold nanoparticles (AuNPs). The shape and size of AuNPs have been successfully controlled by introducing small amounts of L. camara flower extract. It produced spherical nanogold of average size 10.6 ± 2.9 nm without any aggregation and showed significant photocatalytic degradation activity of the methylene blue (>62%, 10 mg/L) in the presence of solar light. In addition, the experimental approach is inexpensive, rapid and eco-friendly for industrial scale production of nanoparticles.
本研究旨在探索马缨丹花在制备金纳米颗粒（AuNPs）方面的潜力。通过引入少量马缨丹花提取物，成功控制了AuNPs的形状和大小。它产生了平均尺寸为10.6±2.9 nm的球形纳米金，且无任何聚集现象，在太阳光存在下对亚甲基蓝表现出显著的光催化降解活性（>62%，10 mg/L）。此外，该实验方法对于纳米颗粒的工业规模生产而言成本低廉、快速且环保。
