Aerosols with nanobots will save our world?

At the Massachusetts Institute of Technology, a technology has developed that embodies fantastic ideas about microscopic helmets in life. This is a spray that contains nanobots, passive automatic sensors configured to recognize specific types of threats. It is enough to spray the aerosol in a dangerous place and count the signal to draw conclusions.

The nanobot consists of a substrate and active part. The first is a colloid, an insoluble particle or a stable molecule. It is too small and light, so due to clashes between themselves and the movement of the atmosphere, the suspension of such particles does not have time to fall to the ground under the influence of gravity, and soars in the air for a long time. If you spray the spray at the beginning of the pipe and serve the air flow through the fan, it will fly through it, collecting information.

The active part of the nanobot is represented by thin, two -dimensional, like graphene, a fragment. It is sensitive to a specific compound, for example, ammonia, after a chemical reaction with it, it sharply improves its electrical conductivity. The simplest photodiode is attached to this material, which produces an electric current when light enters. When the nanobot stumbles upon a scattering of ammonia, its properties change, through the system it skipped the flow of electrons, which is fixed by the memory device. A disposable sensor.

Without a colloidal basis, nanobots will not fly anywhere, but in a conjunction with it they can be passed through both pipes and through the vessels in the human body. It remains only to catch at the exit, at least with the help of a piece of gauze, and then calculate the number of trained nanobots-sensors. And draw a conclusion about the presence of specific substances in the object under study, without the need to penetrate it. How much this will simplify and protect the diagnosis of everything and everything, you can only dream!
