Tiny machines built from individual molecules are moving from science fiction into working hardware, promising to reshape medicine, manufacturing, and even computing. Instead of gears and pistons, ...

Synthetic nanomotors are tiny machines, typically in the range of nanometers to micrometers, that can convert various forms of energy into mechanical motion at the nanoscale. These artificial motors ...

Using laser light instead of traditional mechanics, researchers have built micro-gears that can spin, shift direction, and even power tiny machines. These breakthroughs could soon lead to ...

A tiny machine made from just an atom and particles of light may sound impossibly simple, but it raises a surprisingly difficult question: what counts as heat, and what energy can still do useful work ...

David Leigh dreams of building a small machine. Really small. Something minuscule. Or more like … molecule. “Chemists like me have been working on trying to turn molecules into machines for about 25 ...
