Fig. 8: Camouflaged nanorobots promote recovery in SCI rats.

a Schematic of the experiment timeline. b BBB score for assessment of motor function recovery of the hind limbs (n = 6 independent experiments). c Representative footprints used to assess the recovery of hind limb motor function. Fore limb footprints are shown in blue and hind limb footprints in red (6 independent experiments). d Quantitative analysis of stride length in footprints (n = 6 independent experiments). e Quantitative analysis of angles in the inclined plane test (n = 6 independent experiments). f Electrophysiological analyses of MEPs amplitudes from rats in different groups (6 independent experiments). g Quantification of MEPs amplitudes from rats in different groups (n = 6 independent experiments). h H&E staining of bladders from rats in different groups (scale bars=1 mm, 6 independent experiments). i Quantitative analysis of the maximum bladder wall thickness (n = 6 independent experiments). The data were represented as mean ± SD. Statistical significance was calculated by one-way ANOVA with Tukey’s post hoc test. Source data are provided as a Source Data file.
