Scientists Unveil New Hyper-Raman Technique to Explore Molecular Chirality
Breakthrough method uses chiral light and gold nanohelices to reveal previously hidden molecular properties, promising advancements in multiple fields.
- Hyper-Raman optical activity allows deeper molecular analysis by combining photons to create a single scattered photon with a color change.
- The technique can penetrate living tissues, reducing damage and producing clearer images compared to traditional methods.
- Gold nanohelices amplify the hyper-Raman signal, making the subtle effect detectable.
- Potential applications include pharmaceutical quality control, environmental pollutant detection, and art conservation.
- Collaboration with Renishaw PLC aims to develop the method into a standard analytical tool.
