Abstract

Medication obstruction of microscopic organisms has turned into a worldwide medical issue, as it makes the ordinary anti-toxins less effective. It is desperately expected to investigate novel antibacterial materials and create viable treatment techniques to defeat the medication obstruction of anti-infection agents. Herein, we effectively fabricated silver nanoparticles improved proline/graphene oxide nano-flakes (GO-Pro/n-Ag) as novel anti-pathogenic substance through simplistic technique. The property of the silver nanoparticles activated discharge gave amazing antibacterial and antifungal movement against the pathogenic microorganism. Upon supply of NIR, the graphene oxide based biomaterials privately increased the temperature, bringing about the high mortality of pathogenic microorganism. The GO-Pro biocomposite activated n-Ag particles discharging approach for antibacterial, antifungal enables n-Ag to be ensured by proline layout without influencing normal cells. The biocomposites provided antibacterial and antifungal movement against S. aureus, P.aeruginosa, C. albicans and S. cerevisia. Also, the L929 mouse fibroblast cells were utilized for cytocompatibility assessment, and the GO-Pro/n-Ag demonstrated low lethality. Likewise, the GO-Pro/n-Ag and GO-Pro/n-Ag + NIR are set up for in vivo tests and demonstrate incredible antibacterial property in wound model. As the fabricated GO-Pro/n-Ag biocomposite nano-flakes have the benefits of minimal effort and high anti-pathogenic activity, they may be of promising and helpful antibacterial and antifungal specialists for various biomedical applications.

摘要

微生物药物阻塞已成为全球性的医学问题,因为它使普通抗生素的效果降低。人们迫切希望研究新型抗菌材料并开发可行的治疗技术来克服抗感染药物的药物阻塞。在此,我们通过简单的技术成功制备了银纳米颗粒增强脯氨酸/氧化石墨烯纳米薄片(GO-Pro/n-Ag)作为新型抗病原体物质。银纳米颗粒的活性放电特性赋予了其对病原体微生物的惊人的抗菌和抗真菌活性。在近红外光(NIR)的供应下,基于氧化石墨烯的生物材料会私下提高温度,导致病原体微生物的高死亡率。GO-Pro 生物复合材料通过脯氨酸结构激活 n-Ag 颗粒放电的抗菌、抗真菌作用可确保 n-Ag 不受影响正常细胞。该生物复合材料对金黄色葡萄球菌、铜绿假单胞菌、白色念珠菌和酿酒酵母表现出抗菌和抗真菌作用。此外,还使用 L929 小鼠成纤维细胞进行细胞相容性评估,结果表明 GO-Pro/n-Ag 的致死率较低。同样,GO-Pro/n-Ag 和 GO-Pro/n-Ag+NIR 被用于体内试验,并在伤口模型中显示出令人难以置信的抗菌性能。由于所制备的 GO-Pro/n-Ag 生物复合材料纳米薄片具有成本低和高抗病原体活性的优点,因此它们可能是各种生物医学应用中很有前途且有用的抗菌和抗真菌专家。
