The supramolecule mimics the structure of haemoglobin (below) with iron(III) at it's centre © Wiley-VCHJapanese researchers have created a supramolecule that binds to cyanide ions in a similar way to the blood protein haemoglobin. This could pave the way for faster, more effective cyanide antidotes.The effects of cyanide poisoning are well known to fans of spy stories and murder mysteries. It rapidly shuts down respiration, and high doses can kill in a matter of minutes. Every year, industrial accidents result in several cases of cyanide poisoning, and there is growing concern that it could be used in a terrorist...
