Morphological characterization and measurement of nanoparticles by transmission electron microscopy. A) Electron micrograph of maghemite nanoparticles associated with rhodium (II) citrate (Magh-Rh2(H2cit)4, final concentration: 3.12 × 1013 iron particles/mL). B) Histogram of the distribution of the measured diameters of Magh-Rh2(H2cit)4, with a modal diameter mean of 7.85 nm and σ mean = 2.10. C) Electron micrograph of magnetoliposomes associated with rhodium (II) citrate (Lip-Magh-Rh2(H2cit)4, final concentration: 1.25 × 1013 iron particles/mL). D) Histogram of the distribution of diameters of Lip-Magh-Rh2(H2cit)4 showing a mean modal diameter of 28.19 nm and mean σ = 6.17.
