(A) Fluorescence intensity of rhodamine B (RhB)-doped AuChi-liposome at pH = 1.2 and 7.4, respectively. 0.5 mol% of DMPE-RhB was incorporated into the liposome membranes prior to AuChi stabilization. The binding of AuChi on the liposome would quench the fluorescent probes within the membranes while detaching of AuChi would induce fluorescence recovery. (B) AuChi-liposome solutions after centrifugation to precipitate free AuChi nanoparticles. Dark red color indicates the presence of AuChi in the solution at pH = 1.2 and the sedimentation of AuChi at pH = 7.4.
