Characterization of multimodal nanoparticles 2 (PAA-IONP-DiI). A) Determination of hydrodynamic diameter of the IONPs through Dynamic Light Scattering (DLS), Inset: Transmission Electron Microscope (TEM) image of the corresponding nanoparticles. Scale bar 100 nm. B) magnetic hysteresis loops at 300 and 5 K, showing nanoparticles are superparamagnetic C) fluorescence emission spectra (in PBS buffer) of DiI dye encapsulated IONPs 2 and that of 1 without any dye, D) fluorescence emission spectra of 2 and that of free non-encapsulated DiI in solution.
