(a) Dependence of the VCD enhancement factors \(f_{\textrm{VCD}}(\lambda )\) of the distinct AZO-based nanostructures [Type-1,2, see Figs. 1(a,b)] over the vacuum wavelength \(\lambda\) for aqueous R-Ladarixin with fixed molecular number density \(n_{\textrm{mol}} = n_{\textrm{mol}}^{\mathrm{(R)}} = 10^{-2}\) \(\hbox {nm}^{-3}\) and plasmonic nanoshells with fixed inner radius \(R=100\) nm and thickness \(h = 20\) nm. The blue/red curve indicates \(f_\textrm{VCD}(\lambda )\) of Type-1/Type-2 AZO-based plasmonic nanoshells, respectively. (b,c) Dependence of the absolute value of VCDDA in the presence (\(|\Delta \sigma _{\textrm{abs}}|\)) and absence (\(|\Delta \Sigma _{\textrm{abs}}|\)) of AZO-based nanostructures over \(\lambda\) for (b) Type-1, see Fig. 1(a), and (c) Type-2, see Fig. 1(b), plasmonic nanoshells/nanospheres for \(R = 100\) nm and \(h=20\) nm.
