Researchers print structural colour with an inkjet printer
Summary
Physics World reports on printing structural colour using a silicon nanoparticle ink via inkjet printing. The approach uses Mie resonances, with silica shells preventing nanoparticle aggregation, enabling printable, non-fading colors on flat and 3D surfaces; potential applications include anti-counterfeiting, smart windows, and displays. The work is published in Advanced Materials by Kobe University researchers.
