In 2018, Arthur Ashkin won the Nobel Prize in Physics for inventing optical tweezers: laser beams that can be used to manipulate microscopic particles. While useful for many biological applications, ...

A study published last month by University of Minnesota mechanical engineering researchers has the potential to make waves – ultrasonic waves, to be exact – in fields like surgery and manufacturing. U ...

Over the past several decades, scientists have developed optical and acoustic tweezers. Using light or sound waves, they can lift and control the motion of a small object, like a tiny tractor beam.

Engineers at the University of Minnesota have developed a new system that can move objects without making physical contact. The technique involves ultrasound waves acting on specialized surfaces to ...

Scientists have created a new technology to assemble matter in 3D. Their concept uses multiple acoustic holograms to generate pressure fields with which solid particles, gel beads and even biological ...

No smoke, no mirrors, just sound was all scientists needed to levitate objects in midair. NPR reports that researchers at the University of Tokyo have discovered a new levitation technique through ...
