Fig. 4: Influence of localized surface plasmons of nanoparticles.
a–d Schematic of size variation (a), experimental (b), and theoretical (c) g-factors of single-particle complexes, and electric field intensity as a function of distance from the surface of differently sized AuNPs (d). e, f Schematic (e) and small angle X-ray scattering (SAXS) profiles (f) of superstructures. The cBDP is represented by a red spot, and the DNA linkers are represented by black and green arrows. The inset shows a three-dimensional (3D) tomographic reconstruction of a single superstructure (Supplementary Data 3, Supplementary Movie 1). g, h Extinction and CD spectra of the superstructures and the constituents, respectively. The designation “Satellite” means all small particles (an estimated number of 24) surrounding the core particle. i, j Electric field intensity on the particle surface (i) and in the core-satellite gap (j), excited in the horizontal direction. k Comparison of average |E|/|E0| of satellite particles in superstructures (2nt) and pure satellite complexes (2nt). Core complexes (14nt) were used as a control. l Average |E|/|E0| of satellite particles in different superstructures. Source data are provided as a Source Data file.
