In vivo biodistribution and biosafety of DTP@DMF NPs. a The fluorescence images of mice at different timepoints after DiR-labeled DTP@DMF NPs intratracheal instillation and the fluorescence intensity of major organs after 9 h. b The H&E staining of major organs of mice after DTP@DMF NPs interference. c–k The blood test of mice receiving DTP@DMF NPs. Statistical analyses were performed via one-way ANOVA with S–N-K post hoc analysis (n = 5). * P < 0.05, ** P < 0.01, *** P < 0.001
