Mechanical tuning of gold nanoparticle heptamer. (a)-(b) show the experimentally measured and simulated extinction spectra for mechanical stress along horizontal direction. Stretching direction and polarizations are shown in the insets. Solid line shows experiment results and dashed line shows simulation results. (From Ref. [21])
