Signal modulation under gyromagnetic and magnetomotive (MM) conditions. [48,49] a) Gyromagnetic modulation of polarized scattering using NIR-active gold nanostars; b) periodic changes in intensity as a function of time; c) power spectrum with a characteristic 2ω peak frequency; d–f) MM modulation of polarized scattering using nanostars, similar to above but with a characteristic ω peak frequency; g) spatiotemporal MM modulation using Au@Fe3O4 core–shell nanoparticles.
