Abstract

The present work discloses the use of Erythrina senegalensis leaf extract for reduction of graphene oxide (GO) via a simple one pot technique by avoiding the use of toxic reducing agents. The effective reduction of GO and consequent capping by oxidized plant polyphenols were demonstrated by different spectroscopic and microscopic studies. Fourier-transform infrared (FTIR) spectroscopy indicated the stabilization of RGO with oxidized polyphenols of plant extract. Transmission electron microscopy (TEM) images confirmed the thin, transparent, silk sheet like structure of RGO. Further, the produced RGO displayed a concentration-dependent toxicity toward cardiac cell lines of Catla catla (SICH). In addition, the present study provided the green fabrication of RGO for the development of new products based on graphene for cardiac tissue engineering applications in nursing care.

摘要

本工作公开了塞内加尔刺桐的用途通过简单的一锅技术避免使用有毒还原剂来还原氧化石墨烯（GO）的叶子提取物。通过不同的光谱学和显微学研究证明了氧化型植物多酚有效降低了果糖的含量，并最终封端。傅里叶变换红外（FTIR）光谱表明，RGO稳定于植物提取物的氧化多酚。透射电子显微镜（TEM）图像证实了RGO的薄而透明的丝状结构。此外，所产生的RGO对卡特彼勒的心脏细胞系（SICH）表现出浓度依赖性的毒性。此外，本研究为研发基于石墨烯的新产品提供了绿色的RGO制造，该产品可用于护理领域的心脏组织工程应用。
