Atoms, molecules or even living cells can be manipulated with light beams. At TU Wien a method was developed to revolutionize such "optical tweezers".

Light-based 'tractor beam' assembles materials at the nanoscale

Modern construction is a precision endeavor. Builders must use components manufactured to meet specific standards—such as beams of a desired composition or rivets of a specific size. The building industry relies on manufacturers ...

New scientific concept for a Star Wars-like tractor beam

Physicists from ITMO University have developed a model of an optical tractor beam to capture particles based on new artificial materials. Such a beam is capable of moving particles or cells towards the radiation source. The ...

How to 3-D print your own sonic tractor beam

Last year Asier Marzo, then a doctoral student at the Public University of Navarre, helped develop the first single-sided acoustic tractor beam—that is, the first realization of trapping and pulling an object using sound ...
