Characterisation of liposomes incorporating VP and gold nanoparticles. a Photograph of liposome samples and pure gold colloidal solution. b Absorption spectra of different liposome samples and pure gold colloidal solution. Red arrows indicated typical absorption peaks of VP (~ 410 nm and ~ 689 nm), 5 nm gold nanoparticles (~ 515 nm and 10 nm gold nanoparticles ~ 517 nm). c–e TEM images of 10 nm gold nanoparticles (c) pure liposomes (d) and liposomes loaded with 10 nm gold nanoparticles (e) Red arrows indicate gold nanoparticles encapsulated inside the liposomes
