Star Trek style 'tractor beam' created by scientists
A real-life "Tractor beam", which uses light to attract objects, has been developed by scientists.
It is hoped it could have medical applications by targeting and attracting individual cells.
The research, published in Nature Photonics and led by the University of St Andrews, is limited to moving microscopic particles. Ref. Source 7
Real Life Star Trek Tractor Beam (Hover)
This research looks very promising. I bet we will start to see the first practical applications in a few years. Who knows this technique could lead to important advancements in the treatment of blood cancer and other similar problems? Maybe instead of destroying the damaged cells, along with the good ones, this beam could allow for more selective cures.
