3D Nanostructures: Sculpting Asymmetric, Hollow‐Core, Three‐Dimensional Nanostructures Using Colloidal Particles (Small 11/2015)

A 3D nanolithography technique exploiting particle–light interactions for the low-cost and controllable fabrication of asymmetric hollow-core nanostructures is described by C.-H. Chang and co-workers on page 1285. Multiple oblique illuminations on single particles generate unique complex intensity patterns, which are recorded by underlying photosensitive polymers. The cover depicts nanostructures generated from single, double, triple, and quadruple illuminations. The background image illustrates a non-close-packed polystyrene particle assembly used to fabricate asymmetric nanostructure arrays.
