Abstract

Silver nanoparticles have received much attention, due to their wide range of biological applications as an alternative therapy for disease conditions utilizing the nanobiotechnology domain for synthesis. The current study was performed to examine the antioxidant, anticancer, antibacterial, and antifungal potential of biosynthesized silver nanoparticles (TpAgNPs) using plant extract. The TpAgNPs were produced by reacting the extract and AgNO solution in nine various concentration ratios subjected to bioactivities profiling. According to the current findings, plant extract comprising phenolics, flavonoids, and especially anthocyanins played a critical role in the production of TpAgNPs. UV-visible spectroscopy also validated the TpAgNP formation in the peak range of 401-441 nm. Further, the silver ion stabilization by phytochemicals, face-centered cubic structure, crystal size, and spherical morphology of TpAgNPs were analyzed by FTIR, XRD, and SEM. Among all TpAgNPs, the biosynthesized TpAgNP6 with a medium concentration ratio (5:10) and the plant extract had effective antioxidant potentials of 77.2 ± 1.0% and 45.1 ± 0.5% free radical scavenging activity, respectively. The cytotoxic activity of TpAgNP6 in comparison to plant extract for the rhabdomyosarcoma cell line was significantly the lowest with IC values of 81.5 ± 1.9 and 90.59 ± 1.6 μg/ml and cell viability % of 24.3 ± 1.62 and 27.4 ± 1.05, respectively. The antibacterial and antifungal results of TpAgNPs revealed significant improvement in comparison to plant extract, i.e., minimum inhibition concentration (MIC) 64 μg/ml against Gram-negative while, in the case of antifungal assay, TpAgNP6 was active against . These TpAgNPs play a crucial role in determining the therapeutic potential of due to their biological efficacy.

摘要

由于银纳米颗粒在利用纳米生物技术领域进行合成的疾病状况替代疗法中具有广泛的生物学应用,因此受到了广泛关注。本研究旨在检测使用植物提取物生物合成的银纳米颗粒(TpAgNPs)的抗氧化、抗癌、抗菌和抗真菌潜力。通过将提取物与硝酸银溶液以九种不同浓度比反应来制备TpAgNPs,并进行生物活性分析。根据目前的研究结果,含有酚类、黄酮类,尤其是花青素的植物提取物在TpAgNPs的产生中起着关键作用。紫外可见光谱也验证了在401 - 441nm峰值范围内TpAgNP的形成。此外,通过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)分析了植物化学物质对银离子的稳定作用、TpAgNPs的面心立方结构、晶体尺寸和球形形态。在所有TpAgNPs中,中等浓度比(5:10)生物合成的TpAgNP6和植物提取物分别具有77.2±1.0%和45.1±0.5%的有效抗氧化潜力,自由基清除活性分别为77.2±1.0%和45.1±0.5%。与植物提取物相比,TpAgNP6对横纹肌肉瘤细胞系的细胞毒性活性显著最低,IC值分别为81.5±1.9和90.59±1.6μg/ml,细胞活力百分比分别为24.3±1.62和27.4±1.05。TpAgNPs的抗菌和抗真菌结果显示,与植物提取物相比有显著改善,即对革兰氏阴性菌的最低抑菌浓度(MIC)为64μg/ml,而在抗真菌试验中,TpAgNP6对……有活性。由于其生物学功效,这些TpAgNPs在确定……的治疗潜力方面起着关键作用。
