title: Thermoresponsive assembly of charged gold nanoparticles and their reversible tuning of plasmon coupling.
abstract: Charged colloidal gold nanoparticles (AuNPs) can be assembled and disassembled in an aqueous solution in response to temperature change and display reversible thermoresponsive tuning of plasmon coupling. The reversible tuning was made possible by manipulating the electrostatic interaction through the temperature-dependent zeta potential of the charged AuNPs (see the extinction spectra of a typical AuNP dispersion).
