Iron on antifreeze

An iron-based synthetic compound that mimics the antifreeze effect of natural proteins made by fish that dwell at the poles could be used to halt the formation of ice crystals on airplane wings and perhaps even allow organs for transplant to be frozen for storage without them being damaged by the ice. Matthew Gibson of The University of Warwick, UK, and his colleagues have developed the amphipathic metallohelices and demonstrated their antifreeze effects in the laboratory at concentrations as low as 20 micromolar.
