Abstract

We report the direct observation of the formation and degradation of tensegrity triangle DNA crystals using atomic force microscopy (AFM). We observed the crystal surface by AFM and characterized the lattice coordination of the assembled triangle units at a molecular level. We visualized dynamic formation and degradation of the crystals and characterized them at nano-scale resolution.
