Hybrid, multifunctional nanostructures with diverse 3D shapes and complex material composition can now be manufactured with a precise and efficient fabrication technique
The realisation of nanomachines is inching ever closer to reality. Researchers at the Max Planck Institute for Intelligent Systems in Stuttgart are helping make one of the grand challenges of nanoscience become reality. They have developed a method that makes it possible to manufacture an assortment of unusually shaped and functionalisable nanostructures. It lets them combine materials with widely varying chemical and physical properties at the smallest of scales. The team of scientists headed by Peer Fischer have even grown helical light antennas that are less than 100nm in length from materials which can typically not be shaped at the nanoscale. This is achieved by vapour depositing the material onto a super-cooled rotating disk. Not only does the process allow for the fabrication of nanostructures more exactly than previous methods, several billion of such nanoparticles can be produced in parallel in a rapid manner.
