and the hydrodynamic size of the adducts (DLS in Figure ). As shown, while the overall plasmonic variations are slightly affected by the RRs type, probably due to minimal variation in the viscoelastic rigidity of the membrane induced by the different structures of the RRs molecules, the hydrodynamic size of the AuNPs-vesicles adducts is apparently independent (see the remarkable superimposition of the different DLS curves in Figure ). These easy tunability of the liposomal surface can be exploited to bioconjugate the hybrids with antibodies and introduce targeting specificity.
