- Structural color uses nanostructures to create bright, fade-resistant colors by interacting with light, unlike pigments.
- Conventional structural color methods often cause iridescence, limiting practicality; new research develops a printable nanoparticle ink to overcome this.
- Researchers created a Mie-resonant silicon nanoparticle ink that can be inkjet-printed on flat or 3D surfaces without particle aggregation issues.
- The ink's color is tunable by adjusting nanoparticle size, enabling multi-color patterns with optical asymmetry between reflection and transmission.
- Potential applications include anti-counterfeiting, smart windows, displays, and art, with future goals focused on scalable nanophotonic printing for multifunctional systems.
