Streszczenie

We report on a novel nature-inspired three-dimensional nanoarchitecture of GaN, called aero-GaN or Aerogalnite, which represents the first artificial material with dual hydrophobic-hydrophilic behaviour (see) and exhibits properties close to those inherent to a biological cell membrane. The 3D nanoarchitecture is based on GaN hollow micro-tetrapods with nanoscale thin walls, the inner surface being covered by an ultrathin film of zinc oxide. The hollow micro-tetrapods are shown to self-organize when interacting with water, forming self-healing waterproof rafts with impressive cargo capabilities. Self-propelled liquid marbles based on GaN hollow micro-tetrapods are demonstrated and their rectilinear movement and rotation, including rotation in pulses, are disclosed. The physical properties of aero-GaN will be presented in the context of prospects for applications in various fields. The support from the European Commission under the Grant #810652 "NanoMedTwin" is acknowledged.
