a Simulated scattering, absorption, and extinction cross-section spectra of the hybrid AuND/CB[7]@single MB system with a nanoparticle diameter of 42 nm. b Simulated absorption cross-section spectra of the coupling components of the AuND and MB molecule in the hybrid system. c, d Simulated total scattering and absorption cross-section spectra of the AuND/CB[7]@single MB hybrids, arranged according to the different gap plasmon energies. The colored ball-shaped markers in (c) represent the typical experimental results extracted from Fig. 2b (upper panel). e, f Simulated absorption cross-section spectra of the coupling components of the AuND (e) and the MB molecule (f) in the hybrid AuND/CB[7]@single MB, arranged according to the gap plasmon energies. AuND: Au nanodimer, MB: methylene-blue, Pl: Plasmon.
