Figure 1From: Synthesis route and three different core-shell impacts on magnetic characterization of gadolinium oxide-based nanoparticles as new contrast agents for molecular magnetic resonance imagingTEM images of nanoparticles . TEM images for (a) Gd2O3-DEG, (b) SPGO-mPEG-silane550, (c) SPGO-mPEG-silane2000. Uniformity and spherical or ellipsoidal shape for Gd2O3-DEG and agglomeration for two other nanoparticles are observed.Back to article page
