Assembly-induced microwave band resonance in gold nanoparticles-based ultrathin and flexible spoof localized surface plasmon

DNA-mediated assembly of a gold-nanoparticle film with controllable sonic behavior detected by novel electric-induced ultrasound

“…11 In addition, we also demonstrated an ultrathin and flexible spoof localized surface plasmon (LSP) prepared by the LBL assembly of gold nanoparticles, which was flexible and showed a strong relationship between the resonance frequency and the curvature degree of the spoof LSP. 12 However, in this case the GNPs are in the aggregated state, and thus may result in the loss of some pivotal properties compared with those in the single nanoparticle state. In addition, this method is difficult to control and the assembly films are formed irreversibly.…”
