Silver nanoparticles (AgNPs) have been emerged as significant wound healing agents because of their improved mechanical properties. However, the green synthesized silver nanoparticleshave reported significant wound healing action in Albino rats which was validated by the measurement of wound closure rate. Silver nanoparticles were efficiently synthesized using Euphorbia milii leaf extract. The UV-visible spectra recorded the effect of the reaction time on AgNPs synthesis and was indentified that the peak became shaper with an increase in time, which corresponds to increase in the number of nanoparticles formed from the reduction of silver ions present in the aqueous solution. X-ray diffraction technique and corresponding XRD patterns confirmed the biphasic nature of the biosynthesized silver nanoparticles. However, low magnification TEM images presented monodispersed AgNPs with their size ranging from 20 to 30 nm while SAED diffraction pattern disclosed their crystalline nature. Furthermore, the wound healing activity of AgNPs was examined through the excision wound model by measuring the rate of wound closure and Group II (treated with 10% Ointment base with biosynthesized AgNPs) revealed significant wound healing activity over Control group and Group I (treated with Standard Nitrofurazone ointment) in Albino rats.
银纳米粒子(AgNPs)因其改善的机械性能而成为重要的伤口愈合剂。然而,绿色合成的银纳米粒子已被报道在白化大鼠中具有显著的伤口愈合作用,这通过测量伤口闭合率得到了验证。银纳米粒子是使用大戟叶提取物高效合成的。记录的紫外可见光谱记录了反应时间对 AgNPs 合成的影响,并确定随着时间的增加,峰变得更加陡峭,这对应于从存在于水溶液中的银离子的减少形成的纳米粒子数量的增加。X 射线衍射技术和相应的 XRD 图谱证实了生物合成的银纳米粒子的双相性质。然而,低倍 TEM 图像显示出单分散的 AgNPs,其尺寸范围为 20 至 30nm,而 SAED 衍射图案显示出它们的结晶性质。此外,通过测量伤口闭合率,通过切除伤口模型检查了 AgNPs 的伤口愈合活性,并且在白化大鼠中,第 II 组(用 10%的软膏基质与生物合成的 AgNPs 治疗)显示出比对照组和第 I 组(用标准呋喃西林软膏治疗)显著的伤口愈合活性。
