Image: The plasmon resonance in a gold nanoparticle is exited with light so that the particle appears to have a
color. If there is a change in e.g. the molecules adsorbed onto the catalyst nanoparticles, this will be sensed by the
gold nanoparticles, inducing a change in their color. © The Swedish Research Council
