Nanoscale Asymmetry Leads to Janus-like Nanoparticle MembranesJune 16, 2015

Using grazing incidence small angle x-ray scattering (GISAXS) and surface-enhanced Raman scattering (SERS), very small differences in the distribution of coated-nanoparticle membranes were detected and found to be responsible for their folding into tubular structures. Molecular dynamics simulations show this is related to surface molecular packing density and mobility. Understanding the Janus-like behavior of the man-made membrane opens new design principles to creating 3D artificial superstructures through nanoparticle self-assembly, with opportunities for tuning their electrical, magnetic, and mechanical properties.
