New Molecule With Switchable Chirality

Nanotechnology writes: "Available here, The molecule was developed by adding copper ions to a derivative of the amino acid methionine. The investigators were then able to switch the molecule's chirality by the addition or removal of an electron. Furthermore, they found that the molecule's chirality could be switched repeatedly, and that the two forms of the molecules polarized light in opposite directions." Especially interesting is this line from The Canary Lab's home page ("Research"): "We are also scrutinizing other aspects of signal detection technology. We prepared a new polymer very similar in structure to polyaniline ... The new polymer was designed to serve as a molecular wire for attaching electrochemical sensor molecules to electrodes."
