In this work, we reported a facile method to produce stable aqueous graphene dispersion through direct exfoliation of graphite by modified hyperbranched polyglycerol. Size of graphene sheets was manipulated by simultaneous exfoliation and sonication of graphite, and functionalized graphene sheets with narrow size distribution were obtained. The polyglycerol-functionalized graphene sheets exhibited highly efficient cellular uptake and photothermal conversion, enabling it to serve as a photothermal agent for cancer therapy.
在这项工作中，我们报道了一种通过改性超支化聚甘油直接剥离石墨来制备稳定的石墨烯水分散体的简便方法。通过同时对石墨进行剥离和超声处理来控制石墨烯片的尺寸，从而获得了尺寸分布窄的功能化石墨烯片。聚甘油功能化的石墨烯片表现出高效的细胞摄取和光热转换能力，使其能够用作癌症治疗的光热剂。
