A molecular model shows two macrocycles interlocked like links in a chain, with additional atoms attached on the side of one ring. This conceptual version of the catenane made by Michael Kathan and ...

The structural design of molecular machines and motors endows them with externally controlled directional motion at the molecular scale. Molecular machines based on both interlocked and ...

Scientists have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor proteins make long loops in our DNA, they ...

A University of Texas at Austin-led team has reconstructed the most detailed map to date of the molecular machines that ...

Trying to untangle a knot in a mess of strings can be frustrating and time-consuming. But not so for molecular machines—molecules that convert chemical energy into mechanical work and motion. Machines ...

Fast-scanning atomic force microscopy imaging of the molecule at two different time points shows positional shifts along the polymer chain on the left. On the right, the molecular structure of PEG ...

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, ...

(Nanowerk News) Artificial molecular machines, nanoscale machines consisting of a few molecules, offer the potential to transform fields involving catalysts, molecular electronics, medicines, and ...

Scientists have built DNA-based nanocircuits that reset with heat, enabling reusable molecular systems for tasks like cargo sorting and pattern recognition. (Nanowerk News) Though it might seem like ...

Fraser Stoddart, an organic chemist who shared a Nobel Prize for helping explore the potential of infinitesimal “molecular machines” that could one day revolutionize fields such as medicine and ...
