Gold adds the shine of reversible assembly to protein cages

Protein cages—capsule-like structures made up of numerous protein molecules—perform roles in nature that have inspired their application in areas such as drug delivery. Their controlled assembly is therefore of particular ...

A better trigger for targeted drug delivery

Biomolecular 'nanocarriers' formed by the careful assembly of protein subunits are common in nature and perform a range of essential roles in biological processes, powered by the biological energy carrier adenosine-5'-triphosphate ...

Artificial muscle contracts and expands with changes in humidity

(Phys.org) —A small plastic strip can do "weight training" to effortlessly lifts many times its own weight, driven by cyclic changes in the humidity of the surrounding air. This strong "artificial arm" is based on the interaction ...
