Inkjet Printers Now Capable of Producing Structural Colors
Researchers at Kobe University have created an inkjet‑compatible suspension of silicon nanospheres that produces vivid, non‑fading structural colors on flat and three‑dimensional surfaces. By coating each nanosphere with a thin silica shell, the team prevented particle aggregation, preserving the precise Mie‑resonant optical properties during drying. The ink successfully printed full‑color images on PET film and metallic substrates at 125‑250 dpi, demonstrating dual‑view effects that change under reflected versus transmitted light. This pigment‑free approach promises durable, non‑toxic coloration for a range of industrial and consumer applications.
