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, ...

Biology is full of molecular machines, such as motor proteins and ATP synthase, that operate self-sufficiently through cycles of oxidation and reduction. A team of human chemists at the University of ...

Sir Fraser Stoddart, who has died aged 82, was a phenomenally inventive Scottish-born scientist who shared the 2016 Nobel Prize in Chemistry with the Frenchman Jean-Pierre Sauvage and the Dutch ...

(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 ...

Ferrocene is a key molecule for developing molecular machines. However, it readily decomposes on the surface of flat noble metal substrates, marking a significant challenge. Now researchers have ...

The complex of ammonium-linked ferrocene (Fc-amm) and crown ether is assembled on a Cu(111) surface, and its sliding motion is activated by hole injection into the ferrocene group using scanning ...
