(a) Dependence of the \(\textrm{Re}[\epsilon _{\textrm{AZO}}]\) over \(\lambda\) and plasma wavelength \(\lambda _{\textrm{P}}\)calculated from fitting RDP of AZO39 by the Drude model. (b,c) Dependence of the absorption cross-section upon right circular polarisation excitation \([\sigma _{\textrm{abs}}^{(s=+1)}(\lambda , \lambda _{\textrm{P}})]\) over \(\lambda\) and \(\lambda _{\textrm{P}}\) for (b) Type-1, see Fig. 1(a), and (c) Type-2, see Fig. 1(b), plasmonic nanoshells/nanospheres with fixed radius \(R = 100\) nm and thickness \(h=20\) nm embedding/embedded in pure R aqueous Ladarixin with molecular density \(n_{\textrm{mol}}=n_{\textrm{mol}}^{(\mathrm R)} =10^{-2}\) \(\hbox {nm}^{-3}\).
