Complex, three dimensional (3D) assemblies of nanomaterials provide sophisticated, essential functions in even the most basic forms of life. Compelling opportunities exist for analogous 3D structures in man-made devices, but design options are highly constrained by capabilities in fabrication and growth that are primitive compared to those found in biology. This talk describes a collection of recently developed routes to 3D mesostructures that rely on geometric transformation of lithographically defined two dimensional (2D) precursor micro/nanostructures by controlled processes of compressive buckling. We review the key concepts, and highlight some example applications at the bio-interface.
