Query: Raiders of the lost SAR: Radiofrequency cycles of magnetic nanoflowers
  inside a tumor   Radiofrequency magnetic cycles of \textit{ex vivo} melanoma tumor tissue
loaded with Fe$_3$O$_4$ nanoflowers (NF) were measured for several field
conditions and compared with the cycles of a ferrogel (FG) obtained
incorporating identical NF in agarose gel. Results were studied in order to
understand a reported specific power dissipation (SAR) reduction of the NF in
the actual application medium (tumor) in comparison with a typical
characterization model as the FG. The linearity of the response, together with
coercive field and SAR values were analyzed.\\ Additionally, a novel method for
the determination of the NF mean relaxation time is presented. Results show a
systematic difference in magnetic response between the NF incorporated in the
tumor and those in the FG for all field settings (\{98, 170, 260\} kHz and
\{17.4, 54.0\} kA/m) with SAR reductions above 50\%.
