Characterization of fluorescent magnetic nanoparticles (F-MNPs) and F-MNP-conjugated gentamicin (F-MNP@GM). (A) Transmission electron microscopy (TEM) images of F-MNPs at different magnifications. (B) Photographs of the particle powder and dispersion under visible and UV light. (C) Excitation and emission spectra of F-MNPs. (D) Hydrodynamic diameter, zeta potential, and (E) Fourier transform infrared (FT-IR) spectrum of F-MNPs during the process of drug loading.
