Fig. 9. Entrapment and subsequent release of Rho-B from the vesicular self-assemblies: (A and B) fluorescent micrographs of self-assembled 2d (41 mM) containing Rho-B (0.41 mM) exposed under blue and green emission light, (C and D): fluorescent micrographs after the addition of triton X-100 (0.41 mM) into the Rho-B entrapped vesicular self-assembly of 2d. (E) Fluorescence emission spectra (λ_max(ex.) 520 nm) of free and encapsulated Rho-B inside the vesicular self-assemblies of 2d at different time intervals: (a) = free Rho-B (3.45 μM), (b–d) = 2d (0.345 mM) and Rho-B 1 h, 3 h and 24 h respectively, (F) fluorescence emission spectra of the release of Rho-B by triton X-100 at different time intervals: (e) = 1 h, (f) = 3 h, (g) = 24 h.
