T2 values determined from T2 maps of IONP-doped CPNs at different concentrations.
| Compound | Concentration (mg/L) 1 | T2 (ms) |
|---|---|---|
| CPFeNP | 50 | 37.2 ± 0.8 |
| 25 | 84.3 ± 0.5 | |
| 5 | 237 ± 2 | |
| CPNiNP | 50 | 33.1 ± 0.5 |
| 25 | 106 ± 2 | |
| 5 | 200 ± 2 | |
| CPN/no-met 2 | 20 | 488 ± 7 |
| PBS | - | 508 ± 7 |
1 Concentration expressed in terms of F8BT mass content; 2 CPNs/no-met: nanoparticle without IONPs. IONP-doped CPNs have a CP:IONPs mass ratio of 1:6.8, e.g., for CP concentration = 50 mg/L IONPs concentration = 320 mg/L.
