A colour-changing compound that can precisely indicate the ‘enantiomeric excess’ (ee) of chiral molecules could provide a convenient method to measure pharmaceutical purity. Many molecular systems in ...

Doubly stapled α-helix consisting only of achiral amino acids. Its one-handed form can be isolated because the interconversion between the right- and left-handed forms is almost completely suppressed.

Cage-shaped molecule that changes from left-handed to right-handed when a metal ion enters its inner cavity. The conversion speed varies up to 1000 times depending on the size of the metal ion (K +, ...

Researchers report a new method for distinguishing between enantiomers, molecules that are mirror images of each other. The procedure, relevant for the pharmaceutical industry, involves the chemical ...

Chirality is a fundamental property of asymmetry in nature, where an object or molecule cannot be superimposed onto its mirror image. In the context of nanotechnology, chirality refers to the ...

Any object that cannot be superimposed on its mirror image is said to be chiral. Enantiomers are chiral molecules that contain the same atoms and chemical bonds but exhibit ‘handedness’ — they are ...
