Nanocomposites of diphenylalanine (FF) and carbon based materials provide an opportunity to overcome drawbacks associated with using FF micro- and nanostructures in nanobiotechnology applications, in particular their poor structural stability in liquid solutions. In this study, FF/graphene oxide (GO) composites were found to self-assemble into layered micro- and nanostructures, which exhibited improved thermal and aqueous stability. Dependent on the FF/GO ratio, the solubility of these structures was reduced to 35.65% after 30 min as compared to 92.4% for pure FF samples. Such functional nanocomposites may extend the use of FF structures to e.g. biosensing, electrochemical, electromechanical or electronic applications.
二苯基丙氨酸（FF）与碳基材料的纳米复合材料为克服在纳米生物技术应用中使用FF微米和纳米结构所带来的缺点提供了契机，尤其是其在液体溶液中较差的结构稳定性。在本研究中，发现FF/氧化石墨烯（GO）复合材料能自组装成层状微米和纳米结构，这些结构表现出更好的热稳定性和水稳定性。取决于FF/GO的比例，这些结构在30分钟后的溶解度降至35.65%，而纯FF样品为92.4%。这种功能性纳米复合材料可能会将FF结构的应用扩展到例如生物传感、电化学、机电或电子应用等领域。
