Responsive Photonic Hydrogels Based on Nanocrystalline Cellulose

All in order: The self‐assembly of nanocrystalline cellulose (NCC) with hydrogel precursors leads to nanocomposites with long‐range chiral nematic order. The combination of chiral structure and hydrogel swelling behavior gives rise to iridescence that rapidly responds to various stimuli.
