Magnetization vs. μ 0 H/T plot fit to a Brillouin function of the Gd-SWCNTs.
Magnetization vs. temperature plot for Gd-SWCNTs at applied field of 5 T (blue and red squares represent FC and ZFC data).
(a) r 1 NMRD profile of the Gd-SWCNTs. Circles represent experimental data and solid lines the best fit obtained using SBM theory. (b) r 1 NMRD profile of G2O3 nanoparticles dispersed in 1% Pluronic F127 solutions.
r 2 NMRD profile of the Gd-SWCNTs. Circles represent experimental data and solid lines the best fit obtained using SBM theory.
Contrast-enhanced T 1-weighted (gradient echo sequence; repetition time (TR) = 66 ms, echo time (TE) = 3 ms, flop angle = 108°) MRI phantom images of Gd-SWCNT (green circle), and Gd-DTPA (Magnevist, purple circle) solutions dispersed in 4% gelatin (4 g of gelatin in 100 g of distilled water). Both phantoms have equimolar concentrations of gadolinium ([Gd3+] = 0.22 mM).
