Chemists clarify a chiral conundrum

Chemists at Rice University have discovered that bovine serum albumin is prone to pushing gold nanorods into right-handed chiral assemblies. The work suggests that it may become possible to sense the handedness, or chirality, of single proteins – a potential boon for pharmaceutical companies that require drug purity. A molecule with the correct chirality can save a life, while the same molecule of the opposite chirality can be highly toxic.
