Bacterial infection is a major crisis of 21st era and the emergence of multidrug resistant (MDR) pathogens cause significant health problems. We developed, green chemistry-based silver nanoparticles (G-Ag NPs) using fruit peel extract. G-Ag NPs has a spherical shape in the range of ~ 40 nm with a surface charge of - 31 Mv. This nano-bioagent is an eco-friendly tool to combat menace of MDR. Biochemical tests prove that G-Ag NPs are compatible with human red blood cells and peripheral blood mononuclear cells. There have been many reports on the synthesis of silver nanoparticles, but this study suggests a green technique for making non-cytotoxic, non-hemolytic organometallic silver nanoparticles with a high therapeutic index for possible use in the medical field. On the same line, G-Ag NPs are very effective against sp. and MDR strains including and isolated from patient samples. Based on it, we filed a patent to Indian Patent Office (reference no. 202111048797) which can revolutionize the prevention of biomedical device borne infections in hospital pre/post-operated cases. This work could be further explored in future by in vivo experimentation with mice model to direct its possible clinical utility.

细菌感染是21世纪的一大危机,多重耐药(MDR)病原体的出现引发了严重的健康问题。我们利用果皮提取物开发了基于绿色化学的银纳米颗粒(G-Ag NPs)。G-Ag NPs呈球形,粒径约为40纳米,表面电荷为 - 31毫伏。这种纳米生物制剂是对抗多重耐药威胁的环保工具。生化测试证明G-Ag NPs与人类红细胞和外周血单核细胞相容。关于银纳米颗粒的合成已有许多报道,但本研究提出了一种绿色技术,可制备具有高治疗指数、无细胞毒性、无溶血作用的有机金属银纳米颗粒,有望用于医学领域。同样,G-Ag NPs对从患者样本中分离出的 菌属和多重耐药菌株(包括 和 )非常有效。基于此,我们向印度专利局提交了专利(参考编号202111048797),这可能会彻底改变医院手术前后生物医学设备相关感染的预防。未来可通过小鼠模型进行体内实验进一步探索这项工作,以指导其可能的临床应用。
