Using corkscrew lasers to separate chiral molecules

Many of the molecular building blocks of life have two versions that are mirror images of one another, known as enantiomers. Although seemingly identical, the two enantiomers can have completely different chemical behaviour—a ...

Observing changes in the chirality of molecules in real time

Some molecules can exist in two mirror-image forms, similar to our hands. Although such so-called enantiomers have almost identical physical properties, they are not the same. The fact that they behave to each other like ...

New membrane efficiently separates mirrored molecules

Prof. Liu Bo and colleagues at the University of Science and Technology of China (USTC) have developed a chiral separation membrane capable of capturing left-handed chiral molecules and releasing the right-handed counterpart ...

From mirror-image biology to enhanced therapeutic proteins

Scientists from the German Cancer Research Center (DKFZ) have succeeded in reconstructing biomolecules in their mirror-image form. The researchers' goal is to create a mirror-image artificial protein synthesis system. Their ...

Video: The limonene myth

Limonene, a compound found in citrus fruits, has two enantiomers: mirror-image molecules that cannot be superimposed, like a left and right hand.

Chirality in real time

Distinguishing between left-handed and right-handed (chiral) molecules is crucial in chemistry and the life sciences, and is commonly achieved using a method called circular dichroism. However, during biochemical reactions, ...

Photochemical deracemization of chiral compounds achieved

Enantiomeric molecules resemble each other like right and left hands. Both variants normally arise in chemical reactions. But frequently, only one of the two forms is effective in biology and medicine. Completely converting ...
