Abstract

Monolayers of photothermally responsive gold nanostars on PEI-coated surfaces display two localized surface plasmon resonances (LSPRs) in the near-IR region that can be laser-irradiated either separately, obtaining two different T jumps, or simultaneously, obtaining a T jump equal to the sum of those obtained with separate irradiations.
