Fig. 3From: Magnetic core–shell nanowires as MRI contrast agents for cell trackingVariation of mean signal intensity (± SD, n = 3) with the concentration of MDA-MB-231 cells labeled with APTES-NWs (a) or BSA-NWs (b). Averaged T2* weighted images (acquired at 7 T) of cells are presented at the bottom of the plots, for each cell concentrationBack to article page
