(A) The fluorescent intensity of ARS (0.1 mM) upon mixing with micelles formed by PEG5k-NBA4-CA8 (0.1 mM) with different ratios of PEG5k-Catechol4-CA8 (0-0.5 mM) in PBS at pH7.4. Excitation: 468 nm. (B) Continuous dynamic light scattering measurements of NCM in SDS and BCM4 in SDS for 120 min, at which time mannitol was added or pH of the solution was adjusted to 5.0 (see arrow). TEM images of BCM4 in PBS(C1), BCM4 in SDS for 120 min (C2), BCM4 in SDS for 120 min and then adjusted the pH of the solution to 5.0 for 20 min (C3), and BCM4 in SDS for 120 min and then treated with mannitol (100 mM) for 20 min (C4), (scale bar: 100 nm).
