Theoretical simulations have predicted that a lipid bilayer forms a stable superstructure when a sheet of graphene is inserted in its hydrophobic core. We experimentally produced for the first time a lipid–graphene–lipid assembly by combining the Langmuir–Blodgett and the Langmuir–Schaefer methods. Graphene is sandwiched and remains flat within the hydrophobic core of the lipid bilayer. Using infrared spectroscopy, ellipsometry, and neutron reflectometry, we characterized the superstructure at every fabrication step. The hybrid superstructure is mechanically stable and graphene does not disturb the natural lipid bilayer structure.

石墨烯在脂质双层的疏水核中的包封
理论模拟已预测，当将一片石墨烯插入其疏水核中时，脂质双层会形成稳定的上部结构。我们通过结合Langmuir-Blodgett和Langmuir-Schaefer方法首次实验性地制备了脂质-石墨烯-脂质组装体。石墨烯夹在中间，并在脂质双层的疏水核内保持平整。使用红外光谱法，椭圆偏振法和中子反射法，我们在每个制造步骤中对上部结构进行了表征。杂化上层结构是机械稳定的，并且石墨烯不会干扰天然脂质双层结构。
