Does Tractor waves/Beams exists in real?

Tractor Beam has been a science fiction until certain time. It was the feeling that they are like a  hypothetical beam of energy which can be used to move objects or levitate.

But recent research has shown that sound waves can levitate ( suspend particles) object of different shape,size and material through water,air and tissue. This invention help us to manipulate cells, body fluids, liquids, compounds of different parts without touching or contaminating them. Accessing some of the parts by physical touch can lead to infections. By this invention, the former problems can be eliminated. However, Levitation using acoustic waves requires targets to be enclosed with acoustic elements. The acoustic structures shaped like tweezers,twisters or bottles emerge as the optimum mechanisms for tractor beams. This type of transportation is called container-less transportation. This helps in transporting target drug to the living tissues without disturbing any other tissues.


Levitation of particles of a wide range through air will happen when the radiation forces exerted by the acoustic waves form a acoustic trap and converge.
