Creating a chiral polymer from achiral monomers using a magnetic field

A combined team of researchers from the Weizmann Institute and the Israel Institute of Technology, both in Israel, has developed a way to create a chiral polymer from achiral monomers using a magnetic field as a way to align ...

Making it easier to differentiate mirror-image molecules

Using a new method, scientists are better able to distinguish between mirror-image substances. This is important amongst others in drug development, because the two variants can cause completely different effects in the human ...

Damaged plants and fake perfumes can be identified rapidly and reliably in real time

The chiral signature of a fragrance can reveal whether a perfume is genuine or fake. Similarly, the chiral signature of the emissions of a plant can provide information on whether the plant is healthy or sick. Researchers ...

Tracking chirality in real time

Chiral molecules exist in two forms, called enantiomers, which are mirror images of each other and non-superimposable—much like a pair of hands. While they share most chemical and physical properties, enantiomers can have ...

Researchers develop powerful strategy for creating new-to-nature enzymes

Engineering enzymes to perform reactions not found in nature can address longstanding challenges in the world of synthetic chemistry, such as upgrading plant-based oils into useful biochemicals.

Controlling chemical mirror images

Chirality, while not a rarity in the world of molecules, is nevertheless a special property. If a molecule is chiral (from the Greek word chiros = hand), it exists in two mirrored versions that are very similar but not identical—like ...

Research reveals a new mechanism to transfer chirality between molecules in the nanoscale field

If we compare the right to the left hand, we can see these are specular images—that is, like symmetrical shapes reflected in a mirror—and they cannot superimpose on each other. This property is chirality, a feature of ...

Learning chemical networks give life a chiral twist

When holding a right hand in front of a mirror, one can see a reflected image of a left hand and vice versa. In 1848, Louis Pasteur discovered that organic molecules are much like our hands: they come in mirror-image pairs ...

Chiral gold nanoparticles increase vaccine efficacy by more than 25%, study suggests

Vaccines can be made over 25% more effective by adding left-handed chiral gold nanoparticles as adjuvants, according to a study by an international collaboration in which Brazilian researchers took part. An article reporting ...

Quantum interference directed chiral Raman scattering in 2-D enantiomers

Raman scattering spectroscopy is a necessary and accurate method to characterize lattice structure and probe electron-photon and electron-phonon interactions. In the quantum realm, electrons at the ground states can be excited ...
