Description
Serena Schiavi and a team of chemists grow gold nanoparticle patterns in 2026 using a one-step polymer trick borrowed from mussel-like chemistry. Catecholamine monomers polymerise only where directed, creating chemical contrast on many materials within minutes. Patterns ranged from micrometres down to features a few tens of nanometres wide.
Gold then nucleates exactly on the patterned spots, with particle size and count per spot set by growth conditions. Several patterns were produced side by side on one substrate in a single run. The finished surfaces resonated strongly across visible and near-infrared light, reaching high quality factors. Such ordered plasmonic arrays serve sensing, catalysis, and photonics. The authors stress scale: bottom-up wet chemistry here reaches single-particle precision without slow top-down carving.
