Fig. 1. (a) Distribution of the dynamic diameters of the surface cross-linked micelles (SCMs), and DFMs before and after cross-linking under UV irradiation. (b) Size and particle dispersion index (PDI) of the DFMs after cross-linking or before cross-linking as a function of the concentration of 1 in water. The concentration-independent size indicated the stability of covalently cross-linked DFMs. (c) Transmission electron microscopy (TEM) image (left) and the corresponding photograph (right) of the DFMs in water. (d) Distribution of the hydrodynamic diameters of the DMFs after the addition of 20 μM glutathione (GSH) and removal of the precipitate. (e) TEM micrograph (left) and the corresponding photograph (right) of the DFMs after the addition of 20 μM GSH and removal of the precipitate. (f) The emission spectra of the naphthalene (D) and dansyl-n-butyl sulfonamide (A) incorporated into the micellar SCMs and the DFM core (DFMs@D&A) in water, before (red) and after (olive) addition of 20 μM GSH.
