Peptides fashioned into world’s smallest biomechanically linked structure.

“Most of the mechanically interlocked molecules that form the basis of these molecular machines have so far relied on metal ions and harsh solvents to form the desired structure. Princeton University scientists set out to sidestep the need for artificial building blocks by synthesizing mechanically interlocked molecules entirely from natural biomolecules, in this case the tiny strands of amino acids known as peptides.” | learn more
