Fig 12 The regulation of magnetic circular dichroism (MCD) by the precise assemblies (a, b) CD spectra (top curves) and UV-Vis-NIR spectra (bottom curves) of side by side (SS) assembly (red curves in (a)) or end to end assembly (EE) (pink curves in (b)) by GNRs. Blue curves stand for the corresponding spectra of dispersed GNRs, as reference. Inside are TEM images of SS GNR assembly and EE GNR assembly. Scale bars, 50 nm. (c) Scheme showing the symmetry of TSPR (left) or LSPR (right) mode in single gold nanorods. (d) Diagram of the effect of geometry factor on magnetoplasmonic CD signal upon tuning the aspect ratio or assembly conformation. (a–d) Reprinted with permission from Ref. 215.
