Figure 7 (a) Interaction of BMNPs with 4T1 cells in the presence/absence of a continuous gradient magnetic field analyzed at TEM, micrographs of the cells incubated with the 100 µg/mL of BMNPs for different periods of time. The micrographs are representative of alternate serial cuts of the cell pellets of each sample. Scale bar, 5 µm. (b) In vivo antitumor activity of BMNPs under the influence of AMF, Images were captured using a thermic camera of a representative mouse without (left) and with (right) injected BMNPs during AMF treatment. Note the different colors within the circle on the backside of the mouse.Citation284
