The principle of drones want to be transferred to the nanoscale as well. Nano drones are to be supplied with polarized laser beams both controlled and with drive energy.
The nano drones can only be observed under the microscope. This is the danger of losing sight of them before the researchers can direct the laser beam at them. “We are working on a kind of fencing to restrict the freedom of movement of the Nanodrohnen” , says a physichian expert.
The Goal Of The Researchers Is A New Class Of Nano-Tools
Tools that can be controlled by liquids in a highly precise manner. For example, drones could scan the surface of cells to find certain disease-relevant receptors.
It is also possible to use it as a probe for electrical potential in neural networks. However, all this was conceivable at first only in experiments under the microscope – not within the body as with the famous nano-submarine from the relevant films, says the researcher.
However, the drone consumes a lot of energy and is not suitable for longer distances and transports. This is where the surface model comes into play: In contrast to the futuristic multicopter, these drones look more like an ordinary passenger airplane.
Meanwhile there are also hybrid models, which combine the advantages of both forms: this glider has on the one hand rotors for vertical starting, but also has surfaces for gliding. After the ascent, the drone tilts the rotors and flies on as a plane aircraft. “Hybrid models are still a niche production, but you can see them more and more.
