Russian scientists introduced micro-vacuum cleaner to help clean the environment from harmful particles

A research team from Tomsk Polytechnic University has developed an optical vacuum cleaner that maximizes cleaning of the environment and rooms from harmful particles.

The research results are published in Scientific Reports.

The invention will help the room to be exceptionally clean by removing harmful nanoparticles. This is done by controlling the movement of these particles.

Optical radiation on the particle will be fixed, concentrated near its surface.

"The idea of ​​making an optical vacuum is quite simple. A mesoscale dielectric particle is used - in this case, the particle has a cube shape - with an index of refraction versus an environment that is approximately equal to 2. Through this, the optical radiation on the particle will be fixed, concentrated near its surface, " said research project leader Oleg Minin.

According to the scientists, if a small hole is made in the particle, then under the influence of optical power, the nanoparticle will be 'pulled' into it.

Because microparticles are only 1 to 10 wavelengths of radiation, this method will allow the creation of micro systems to clean the environment on the chips.
