Scientists have developed an optical vacuum cleaner for nanoparticles

A group of scientists have developed the concept of an optical vacuum cleaner that is capable of effectively trapping nanoparticles from the environment. The technology will allow you to purify the air for laboratory research and preparation of clean rooms.

Researchers around the world are currently looking for ways to manipulate and manipulate tiny particles ranging in size from 1 nm to 100 nm for a variety of purposes. Until now, there has not been a sufficiently effective and widely used device for such tasks..

However, scientists from Tomsk Polytechnic University, together with foreign colleagues, proposed the concept of a photonic «microvacuum cleaner». It is a microscopic dielectric cube with a nanoscale hole.

Under the influence of optical radiation, light pressure arises, the resulting force of which is directed into the device, due to which nanoparticles are attracted into the hole.

The optical vacuum cleaner can be used for several functions in the operation of micro laboratories for medical and biological research, as well as cleaning the air and surfaces of foreign particles.

Next, scientists will test the practical application of the concept.
