Physical properties of FA-NPs. (A and B) DLS and TEM characterization confirms NPs are under 100 nm diameter (82.3 ± 8.4 nm hydrodynamic diameter). (C) FA-NPs retain the excitation and emission (λex = 581 nm, λem = 605 nm) spectra of the parent FA molecule. (D and E) The critical micelle concentration of NPs was determined as ~ 0.065 mg/mL by nile red assay and observation of size and morphological changes by DLS. (F) NPs release drug dose-dependently in response to increasing H2O2.
