In this study, NMR spectroscopy has been utilized to investigate the supramolecular nanostructures including host-guest complexes and self-assemblies. Materials with nanoscale pores such as dendrimers and cyclodextrins were used as the hosts for the complexes, or templeates for the self-assemblies; and the guests studied included pharmaceutical drugs, amino acids and fatty acids. Atomic force microscopy (AFM) was used to probe the dendrimer based self-assemblies, which provides the information on the sizes and interactions of the system by vivid AFM topographic images and force distance curves.
