Self-Healing Stretchable Wires
This video depicts self-healing stretchable wires formed by embedding liquid metal alloy in microchannels composed of self-healing polymer. These stretchable wires can be completely severed with scissors and rapidly self-heal both mechanically and electrically at ambient conditions. By cutting the channels strategically, the pieces can be re-assembled in a different order to form complex microfluidic [...]
Rotaxane mimics ribosome to spin out peptides
10 January 2013 Laura Howes The field of molecular machines has taken a new bio-inspired turn to assemble another molecule, in this case linking up individual amino acids into a peptide. While this molecular peptide synthesiser isn’t going to rival a ribosome for speed any time soon, it does suggest a way to make multicomponent [...]
