Bengaluru researchers mimic nature to produce richer colour

In a novel approach that mimics nature, Bengaluru-based researchers have designed crystalline materials that selectively scatter specific colours of light. Dyes and pigments produce colour predominantly through selective absorption of light. But scattering of light by particles which are arranged in an ordered, periodic pattern produces structural colour, which gives butterfly wings their colour and sheen.


The novel approach adopted by researchers at the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) and Indian Institute of Science (IISc) in Bengaluru has overcome the challenge of transporting the particles to target sites; the size and symmetry of the growing crystallites are also controlled. The results were published in the journal Proceedings of the National Academy of Sciences.
