我们提出了一种简单、低成本和绿色的方法，通过超声波将石墨在水牛血清白蛋白（BSA）溶液中制备稳定的水石墨烯分散体，用于生物医学应用。通过显微镜图像、拉曼光谱、紫外-可见光谱和XPS证实了高质量石墨烯的生产。此外，从头计算揭示了石墨烯和BSA之间的分子相互作用。通过制备导电和机械坚固的水凝胶-石墨烯材料，证明了水凝胶-石墨烯分散体的可加工性。
We proposed a facile, low cost, and green approach to produce stable aqueous graphene dispersions from graphite by sonication in aqueous bovine serum albumin (BSA) solution for biomedical applications. The production of high-quality graphene was confirmed using microscopy images, Raman spectroscopy, UV-vis spectroscopy, and XPS. In addition, ab initio calculations revealed molecular interactions between graphene and BSA. The processability of aqueous graphene dispersions was demonstrated by fabricating conductive and mechanically robust hydrogel-graphene materials.
