Duplicate or mirror? Laser light determines chirality of molecules

Seven of the ten most frequent medications contain chiral agents. These are molecules that occur in right- or left-handed forms. During chemical synthesis both forms usually occur in equal parts and have to be separated afterward, because chirality determines the agent’s effect in the body. Physicists at Goethe University have now succeeded in using laser light for the purpose of creating either right- or left-handed molecules.
