In this present investigation, AgNPs were green synthesised using Coriandrum sativum leaf extract. The physicochemical properties of AgNPs were characterised using UV-visible spectrophotometer, field emission scanning microscopy/energy dispersive X-ray (FESEM/EDX), Fourier transformed infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and Brunauer-Emmett-Teller (BET) analysis. Further, in vitro anti-acne, anti-dandruff and anti-breast cancer efficacy of green synthesised AgNPs were assessed against Propionibacterium acnes MTCC 1951, Malassezia furfur MTCC 1374 and human breast adenocarcinoma (MCF-7) cell line, respectively. The flavonoids present in the plant extract were responsible for the AgNPs synthesis. The green synthesised nanoparticles size was found to be ≈37nm. The BET analysis result shows that the surface area of the synthesised AgNPs was found to be 33.72m(2)g(-1). The minimal inhibitory concentration (MIC) of AgNPs for acne causative agent P. acnes and dandruff causative agent M. furfur was found to be at 3.1 and 25μgmL(-1), respectively. The half maximal inhibitory concentration (IC50) value of the AgNPs for MCF-7 cells was calculated as 30.5μgmL(-1) and complete inhibition was observed at a concentration of 100μgmL(-1). Finally, our results proved that green synthesised AgNPs using C. sativum have great potential in biomedical applications such as anti-acne, anti-dandruff and anti-breast cancer treatment.
在本研究中,利用香菜叶提取物绿色合成了银纳米颗粒。使用紫外可见分光光度计、场发射扫描显微镜/能量色散X射线(FESEM/EDX)、傅里叶变换红外光谱(FT-IR)、X射线衍射(XRD)和布鲁诺尔-埃米特-泰勒(BET)分析对银纳米颗粒的物理化学性质进行了表征。此外,分别针对痤疮丙酸杆菌MTCC 1951、糠秕马拉色菌MTCC 1374和人乳腺腺癌(MCF-7)细胞系,评估了绿色合成银纳米颗粒的体外抗痤疮、抗头皮屑和抗乳腺癌功效。植物提取物中存在的黄酮类化合物负责银纳米颗粒的合成。发现绿色合成的纳米颗粒尺寸约为37nm。BET分析结果表明,合成的银纳米颗粒的表面积为33.72m(2)g(-1)。发现银纳米颗粒对痤疮病原体痤疮丙酸杆菌和头皮屑病原体糠秕马拉色菌的最低抑菌浓度(MIC)分别为3.1和25μgmL(-1)。银纳米颗粒对MCF-7细胞的半数最大抑制浓度(IC50)值计算为30.5μgmL(-1),在浓度为100μgmL(-1)时观察到完全抑制。最后,我们的结果证明,利用香菜绿色合成的银纳米颗粒在抗痤疮、抗头皮屑和抗乳腺癌治疗等生物医学应用中具有巨大潜力。
