Nanoscale Cubes and Spheres

Abstract:
Porous nano-objects with defined sizes and structures are particularly interesting, for example, as capsules for enzymes, a means of transport for pharmaceutical agents, or building blocks for larger nanostructures. The production of such tiny, three-dimensional objects in a targeted and controlled manneróand as simply and efficiently as possibleóremains a challenge for scientists. At the University of Minnesota, a team led by Andreas Stein has now developed an interesting new process for the production of nanoscopic cubes and spheres of silicon dioxide. The researchers reported their trick in Angewandte Chemie: Instead of building their particles from smaller units, they used the controlled disassembly of larger, lattice-like structures.
