Modern biotechnology urgently needs instruments that can move single cells and other tiny objects. The earliest instrument of this kind, laser tweezers, was developed by American Physics Group in 1986. Since then, there have been new technological breakthroughs in this field every year. The research teams of saratov National University of Technology and Tantal Scientific Research Co., Ltd. proposed and designed laser tweezers, which can hold and move up to seven tiny objects at the same time.

19 10, Russian physicist Peter lebedev (петрлебедев) discovered the pressure of light waves and took the lead in using a precise laser microcontroller. It is this pressure that pulls the electrolyte particles to move to the place irradiated by the focused laser, so that the tiny objects move along the focused light.
