Nanoparticles are valuable materials with widespread use. The fact that these materials are obtained by biological resources with an environmentally friendly method contributes to the development of studies in this field. Gold nanoparticles (AuNPs) from waste vegetable sources (green leaves of Capsicum annum L.) are economically and easily synthesized. The obtained particles are characterized by UV–vis spectroscopy (UV–vis), Fourier transform infrared spectroscopy (FTIR), X‐ray diffraction (XRD), and scanning electron microscopy (SEM) analysis. The antimicrobial activity of the particles on the pathogenic microorganisms Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 29213, Bacillus subtilis bacteria, and Candida albicans yeast are found to have a significant suppressive effect. The removal activities of eight toxic metals (Pd, Cd, Fe, Ni, Co, Mn, Zn, Pb) in Diyarbakır drinking water and artificially prepared water within different pHs are investigated. Gold nanoparticles synthesized from Capsicum annuum L. leaves are found to be effective in toxic metal removal in water samples.

植物基合成（辣椒叶）环保金纳米材料的抗菌和有毒金属去除活性的测定。

纳米颗粒是具有广泛用途的有价值的材料。这些材料是通过生物资源以环境友好的方法获得的，这一事实有助于该领域研究的发展。从废弃蔬菜源（ Capsicum annum L.的绿叶）中合成金纳米颗粒（AuNP）既经济又容易。所获得的颗粒通过紫外可见光谱（UV-vis）、傅里叶变换红外光谱（FTIR）、X射线衍射（XRD）和扫描电子显微镜（SEM）分析进行表征。该颗粒的抗菌活性被发现对病原微生物大肠杆菌ATCC 25922、金黄色葡萄球菌ATCC 29213、枯草芽孢杆菌、白色念珠菌有显着的抑制作用。研究了不同 pH 值下迪亚巴克尔饮用水和人工配制水中 8 种有毒金属（Pd、Cd、Fe、Ni、Co、Mn、Zn、Pb）的去除活性。研究发现，从Capsicum annuum L. 叶子合成的金纳米颗粒可有效去除水样中的有毒金属。
