(a, A) Schematic illustration of LSPR excitation for GNSs [8]. (a, B) A typical LSPR absorption band of GNSs. (b, A) Schematic illustration of LSPR excitation for GNRs and (b, B) LSPR absorption bands of GNRs: longitudinal and transverse plasmon bands corresponding to the electron oscillation along the long axis (b, A (top)) and the short axis (b, A (below)) of GNR, respectively [9].
