British scientists have managed to create the smallest engine in the world. The tiny motor, the dimensions of which are equal to a few billionths of a meter, was not developed at all to surprise the public with its diminutiveness - the motor should contribute to the development of medicine, namely those areas that are exploring the possibility of creating microscopic robots with the help of which the therapy of the future will be carried out.
The design of the nanomotor is based on gold particles bound by a polymer gel and coated with special molecules that react to temperature. The principle that makes the structure move is the accumulation and subsequent release of energy transmitted to the motor by means of a laser. Something like a steam engine, but only laser and microscopic.
The creation of an efficient microscopic propulsion system is one of the key problems in the development of nanomachines of the future, which will be injected directly into the human body and deal with the diagnosis and treatment of various diseases. The invention of scientists from Cambridge, according to independent researchers, brings humanity closer to the era of nanotechnological medicine.
