Fig. 5

Hearts were removed from male rats and perfused with Custodiol HTK solution. Then, the heart was perfused with mCPA containing 5 mgFe/ml. The perfused heart was submerged in mCPA and vitrified in a mechanical freezer at a cooling rate of 15°C/min, followed by storage in liquid nitrogen for 1 week. Nanowarming was performed in an AMF (42.5 kA/m and 278 kHz, achieving heating rates above the CWR of 50°C/min for VS55. The SPIONs were perfused out of the heart using Custodiol HTK, followed by MPI to quantify the SPIONs remaining in the hearts. LN2, liquid nitrogen.
