A small team of physicists at the University of Amsterdam has demonstrated the ability of 3D-printed particles to propel themselves across the surface of a fluid, given the right fuel. The group has ...

A levitating magnetic microrobot autonomously sorts sub-millimeter particles by weight in 3D environments, enabling precise, contamination-free handling in biomedical and manufacturing applications.

Scientists have created “acoustic holograms” that can assemble matter into 3D objects, using just sound. The technique works with various types of particles and even living cells, allowing for a new ...
