Figure 1From: Advantages of gadolinium based ultrasmall nanoparticles vs molecular gadolinium chelates for radiotherapy guided by MRI for glioma treatmentStudy of the degradation of the nanoparticle in diluted media after dilution at 2.5 mM. a) Black circles correspond to temporal evolution of the hydrodynamic diameter. b) Temporal evolution of the longitudinal relaxivity. In the two cases, red lines correspond to monoexponential decay fit.Back to article page
