Abstract

: Metallic NPs have been explored for various therapeutic uses owing to utilitarian physicochemical characteristics such as antibacterial, anti-inflammatory, and healing properties. The objective of this study is to evaluate the therapeutic potential of novel silver carbonate nanostructures in promoting wound healing and their antibacterial activity against and . : In this work, we prepared AgCO nanoparticles through a two-step methodology that was expected to improve the material's biomedical performance and biocompatibility. The characterization and assessment of synthesized NPs biocompatibility were conducted using hemolysis assays on the blood of a healthy male human. Further, we performed molecular docking analysis to confirm interactions of silver NPs with biological molecules. : In detail, the synthesized NPs showed <5% hemolysis activity at various concentrations, confirming their therapeutic applicability. Additionally, the NPs had good metabolic activities; they raised the T3/T4 hormone content and acted effectively on Insulin-like Growth Factor 1 (IGF-1) in diabetic models. They also facilitated the rate of repair by having the diabetic wounds reach 100% re-epithelialization by day 13, unlike the control group, which reached the same level only by day 16. The synthesized AgCO NPs exhibited high antimicrobial potential against both and hence being a potential material that can be used for infection control in biomedical tissue engineering applications. : These findings concluded that novel synthesis methods lead to the formation of NPs with higher therapeutic prospects; however, studies of their metaphysical and endocrinological effects are necessary.

摘要

由于具有抗菌、抗炎和愈合等实用的物理化学特性,金属纳米颗粒已被探索用于各种治疗用途。本研究的目的是评估新型碳酸银纳米结构在促进伤口愈合方面的治疗潜力及其对[具体细菌1]和[具体细菌2]的抗菌活性。

在这项工作中,我们通过两步法制备了碳酸银纳米颗粒,预期该方法能提高材料的生物医学性能和生物相容性。使用健康男性的血液进行溶血试验,对合成的纳米颗粒的生物相容性进行了表征和评估。此外,我们进行了分子对接分析,以确认银纳米颗粒与生物分子的相互作用。

具体而言,合成的纳米颗粒在不同浓度下的溶血活性均<5%,证实了它们的治疗适用性。此外,这些纳米颗粒具有良好的代谢活性;它们提高了T3/T4激素含量,并在糖尿病模型中对胰岛素样生长因子1(IGF-1)产生有效作用。它们还促进了修复速度,使糖尿病伤口在第13天达到100%重新上皮化,而对照组直到第16天才达到相同水平。合成的碳酸银纳米颗粒对[具体细菌1]和[具体细菌2]均表现出高抗菌潜力,因此是一种可用于生物医学组织工程应用中感染控制的潜在材料。

这些发现得出结论,新型合成方法导致形成具有更高治疗前景的纳米颗粒;然而,有必要对它们的超自然和内分泌学效应进行研究。
