Photonic gel crystals reflect light based on the way their molecules are "tuned."
Photonic gel crystals demonstrate the "tunability" of materials made from alternating layers of hard and soft polymers. The soft polymers are easily swollen with liquid or vapor, causing the materials to reflect different colors of light based on the way their molecules are chemically "tuned".
