we report the directed arrangement of inorganic nanoparticles into arrayed structures

with long-range order, up to tens of microns, by using hexagonally-packed cylindrical patterns of block copolymernanosheets self-assembled within collapsed emulsion droplets as scaffolds. This technique can be used to generate nanoparticle arrays with various nanoparticle arrangements, including hexagonal honeycomb structures, periodic nanoring structures, and their combinations. This finding provides an effective route to fabricate diverse nanoparticle arrayed structures for the design of functional materials and devices.
