Figure 6. The cardioprotective activity of Fe2O3@DMSA NPs is dependent on their core sizes in guinea pig Langendorff heart following IR.
(a) TEM image of Fe2O3@DMSA NPs of 35.2 nm. (b) Injured hearts were treated with Fe2O3@DMSA NPs of different sizes and then examined for LVDP recovery. * p < 0.05 vs the IR group; ** p < 0.01 vs the IR group; n = 6.
