aerotaxy
With aerotaxy...nanowires are continuously formed on tiny gold balls as they are floating along down a gas-filled chamber, Epstein says.
Aerotaxy comes from Greek roots meaning "air," and "arrangement, order." In aerotaxy, particles organize themselves in a stream of flowing gas. Aerotaxy is contrasted with epitaxy, where crystals are formed on a crystalline substrate which determines the orientation of their growth.
