摘要
Stiff spheres: AFM experiments using a diamond-tip cantilever show that aromatic dipeptide nanospheres (see picture) have a remarkable metallic-like Young's modulus of up to 275a GPa. This exceptional value places these nanostructures as the stiffest organic materials reported to date, thus making them attractive building blocks for the design and assembly of ultrarigid composite biomaterials.
