Bioimaging and therapeutic effects of RCMNs in ALI mouse model. A The distribution of RCMNs was observed in vivo in both healthy and ALI mice following a 2 h injection, and statistics were collected on the intensity of red fluorescence in the mice. B The distribution of RCMNs in the primary organs of healthy and ALI mice was examined, along with a statistical analysis of the corresponding red fluorescence intensity. C The histological images depict H&E-stained lung sections, and the lung injury score was determined by evaluating five pathophysiological characteristics observed in these images. The scale bar represents 50 μm
