Figure 2. Comparison of amplitude-dependent SLP across peak-to-peak field amplitude spectrum among tested nanoparticle formulations. SLP values for Feridex were obtained from Bordelon et al. [Citation6], and are provided for comparison. Error bars represent standard deviation of the mean calculated from three measurements. AMF frequency was 155 ± 10 kHz.
