Polymerisation in the interference pattern's bright regions drives the formamide to the darker regions
A polar solvent is the key to making polymeric photonic crystals that could be used as biological sensors, say scientists from Taiwan and the US.
Alexander Cartwright, at the State University of New York, Buffalo, US, Vincent Hsiao, at the National Chi Nan University, Puli, Taiwan, and colleagues used a method known as holographic photopatterning to make their photonic crystals.
