In recent times, there has been growing interest in nanoparticles (NPs) synthesized through biological means due to their ease of production and their potential applications in the field of biology. This study presents an environmentally friendly method for the biogenic synthesis of silver nanoparticles (AgNPs) using the leaf extract of as both a reducing agent and a capping agent. Various physico-chemical and microscopic techniques were employed to comprehensively characterize the biogenically produced AgNPs. The results of these characterization studies confirmed the formation of spherical, stable, and crystalline AgNPs with an average size of 30.5 ± 2.5 nm. Furthermore, the antibacterial assessment revealed the remarkable antibacterial properties of these biogenically synthesized Ag NPs, even at exceedingly low concentrations ranging from 50 to 100 μg/mL. The IC values for the biogenically synthesized AgNPs against different human cancer cell lines, such as A549, MDA-MB-231, HepG2, and MCF-7, were determined to be 93.4 ± 4.5, 82.5 ± 3.7, 87.6 ± 4.1, and 57.3 ± 2.5 μg/mL, respectively. Most notably, the biogenically synthesized Ag NPs exhibited significant anti-inflammatory activity, as evidenced by their IC value of 30.08 ± 1.4 μg/mL, as assessed through the HRBC membrane stabilization method. These findings strongly suggest that AgNPs fabricated through biogenic processes using leaf extract hold promise as potential therapeutic candidates for combating bacterial infections, cancer, and inflammatory conditions.
近年来,由于通过生物手段合成的纳米颗粒(NPs)易于生产及其在生物学领域的潜在应用,人们对其兴趣日益浓厚。本研究提出了一种环境友好的方法,使用[植物名称]叶提取物作为还原剂和封端剂进行生物合成银纳米颗粒(AgNPs)。采用了各种物理化学和显微镜技术对生物合成的AgNPs进行全面表征。这些表征研究结果证实形成了平均尺寸为30.5±2.5nm的球形、稳定且结晶的AgNPs。此外,抗菌评估显示这些生物合成的Ag NPs具有显著的抗菌性能,即使在50至100μg/mL的极低浓度下也是如此。生物合成的AgNPs对不同人类癌细胞系(如A549、MDA - MB - 231、HepG2和MCF - 7)的IC值分别测定为93.4±4.5、82.5±3.7、87.6±4.1和57.3±2.5μg/mL。最值得注意的是,通过HRBC膜稳定化方法评估,生物合成的Ag NPs表现出显著的抗炎活性,其IC值为30.08±1.4μg/mL。这些发现强烈表明,使用[植物名称]叶提取物通过生物过程制造的AgNPs有望成为对抗细菌感染、癌症和炎症性疾病的潜在治疗候选物。
