Inspired by the cell membrane structure, researchers, led by Dr. Xiaoqing Huang (State Key Laboratory of Physical Chemistry of Solid Surfaces, College of Chemistry and Chemical Engineering, Xiamen University) and Dr. Qi Shao (College of Chemistry and Chemical Engineering and Materials Science, Soochow University), propose a biomimetic strategy for synthesis of nanovesicles by utilizing the interfacial strain as the driving force to curl the ultrathin nanosheets into nanovesicles.
