Mobile molecular robots swim in water

Creating molecular microrobots that mimic the abilities of living organisms is a dream of nanotechnology, as illustrated by the renowned physicist Richard Feynman. There are a number of challenges in achieving this goal. ...

Microscopic metavehicles powered by nothing but light

Researchers from Chalmers University of Technology, Sweden, have succeeded in creating tiny vehicles powered by nothing but light. By layering an optical metasurface onto a microscopic particle, and then using a light source ...

Surprisingly strong and deformable silicon

Researchers at ETH and Empa have shown that tiny objects can be made from silicon that are much more deformable and stronger than previously thought. In this way, sensors in smartphones could be made smaller and more robust.

New rules illuminate how objects absorb and emit light

Princeton researchers have uncovered new rules governing how objects absorb and emit light, fine-tuning scientists' control over light and boosting research into next-generation solar and optical devices.

Levitating objects with light

Researchers at Caltech have designed a way to levitate and propel objects using only light, by creating specific nanoscale patterning on the objects' surfaces.
