Operando Colorations from Real‐Time Growth of 3D‐Printed Nanoarchitectures (Adv. Mater. 41/2024)

3D-Nanoprinted Color Animations As the periodic metallic nanostructures grow simultaneously during nanoprinting, their interaction with light changes, producing a dynamic evolution of colors. Bingyan Liu, Qiling Liu, and Jicheng Feng devise an integrated system that enables the continuous recordings of these color changes both visually and spectrally, mapping out the relationship between structural geometries and optical properties in unprecedented details.
