Molecular MRI-based detection of PBT cells using biofunctionalized Prussian blue nanoparticles. (A) T1-weighted and T2-weighted contrast enhancement in phantoms comprised of a fixed number of BSG D10 treated with MnPB-A488-ANG2 (n=6), MnPB-A488-AbC (n=3), or MnPB-A488 (no antibody, triplicate). (B) Normalized fluorescence signal intensity (au) for BSG D10 treated with ANG2, AbC, and no antibody-modified MnPB-A488. **P<0.05.
