Effects of nanoparticles on biosafety in mice. BALB/c male mice were treated intratracheally with 50 µL of 0.9% normal saline or 10 µM CM-NP-Q in 0.9% normal saline (NS) for 24 h (n = three/group). (A) The serum levels of aspartate transaminase (AST) and alanine transaminase (ALT) were analyzed as described in Materials and Methods. The data points represent the means of three mice ± SD. (B) Histological images of representative lung section. Scale bar = 250 μm
