A Completely New Form of Light Has Been Created: The Chiral Vortex

A fresh type of light structure that has emerged most recently is the chiral vortex. According to the group of the international scientists who worked on its creation, this technology has a great potential to further advance the creation of new drugs and enhance the diagnostics of diseases.

The chiral vortex, as the name suggests, is a light vortex where light spirals as it develops and chirality, a typical feature of molecules and ion that can exist in left or right-handed mirror image resembling the human hand.

This way the light can be made chiral at every point and therefore measurement of chirality in molecules can be done with increased precision. Geometric feature such as handedness of molecules is critical in explaining the functioning of the molecules and their effects on the body either as a benefit or harm.

The Novosibirsk physicist Olga Smirnova cites the newest studies saying that the ratios of the left- and right-handed molecules might serve as the biomarkers for cancers, torionosis of the kidneys and the brain.

Chirality is also essential in drug development something that many people do not understand apart from identifying diseases. Departures from the exact atomic structure of the drugs impact on the scientific work and can have far reaching health consequences.

That is the kind of mistake that the new technology is designed to eliminate. When the chiral vortex is around chiral molecules the molecules fluoresce or emit photons. The pattern of these photons when analysed will help scientists measure the amount of left-handed and right handed molecules that are in existence.

While there already is a way of determining chirality, the researchers said that the chiral vortex presents a more reliable, accurate and inexpensive method. It is less likely to require a large sample-size in order to provide better results but still is in its infancy and requires additional advancements in order to meet greater demands.

The author, Nicola Mayer, a physicist from the Max Born Institute, says that ‘Traditional ways of characterizing chirality have faced challenges in determining the concentration of R- and S-molecules in samples that contain almost equal portions of the two. ’

‘Our new approach can detect any slight predominance of one pure stereo isomer over the other, which may amount to much. ’

It is still not very clear how chirality began but theories suggests that it may have began from space and became one of the key features in many things that exist in the earth. A critical achievement is enhanced differentiation of chiral molecules.

Further, this technology can find other applications including in the manipulation of light matter interactions as well as the ability to control chemical reactions using light.

‘These signals can tell how electrons in molecules move at their optimal speed’, notes Mayer. ”This knowledge could pave way for controlling the movement of electrons and in the long run control chemical reaction with light. ”
