Optical tweezers make 3D structures 17 Jun 2002 Research published in today's Science reveals a simple method to manipulate 3D structures with light beams. By interfering two laser beams, scientists ...

That's because these tweezers are made of sound waves and don't actually touch the cells. The team has been working on the method for quite some time, but their most recent paper discusses how it ...

Researchers report a practical realization of holographic acoustic tweezers, in which ultrasonic waves produced by two arrays of 256 sound emitters were used to trap and individually manipulate up ...

Three-dimensional (3D) imaging is essential for investigating cellular structure and dynamics. Traditional optical methods rely on adhesive or mechanical forces to hold and scan cells, which limit ...

A holographic acoustic tweezers (HAT) system has been used to suspend up to 25 objects in mid-air simultaneously. The feat was achieved by Bruce Drinkwater at the University of Bristol in the UK and ...

After stacking particles in a single column, Kishan Dholakia and colleagues from St Andrews University, UK, set about extending this effect. "Particles get drawn into the bright region, near the focus ...
