MAGCIT–MB ultrastructure and characterization. a, b Colloidal stability of MAGCIT–MB, Hydrodynamic diameter (HD), zeta potential (ZP) and polydispersity index (PDI) over 180 days (a) and pH variation (b) measured by dynamic light scattering. c Rounded morphology of MAGCIT–MB assessed by TEM at 80 kV. Scale bar = 100 nm. d Nanoparticle size distribution of MAGCIT–MB had an average size of 34 ± 9 nm; measurements were performed using ImageJ software. e FTIR spectra of MB, MAGCIT and MAGCIT–MB. f UV–Vis spectra of individual MAGCIT suspensions at different concentrations (7.8 mg L−1, 5.8 mg L−1, 3.9 mg L−1, 2.9 mg L−1 and 1.9 mg L−1) and MB solution (upper panel), and spectra of MAGCIT–MB with different MAGCIT concentrations, as indicated (lower panel)
