Fig. 5From: Selectively down-regulated PD-L1 by albumin-phenformin nanoparticles mediated mitochondrial dysfunction to stimulate tumor-specific immunological response for enhanced mild-temperature photothermal efficacyPharmacokinetics and bio-distribution of ICG@PM@NP in vivo. A Real-time NIR fluorescence images of the CT26 tumor-bearing mice after intravenous injection of ICG@NP or ICG@PM@NP at different time points. B–E Quantification of ICG or PM concentration in tumors and normal tissues at 24 h or 48 h after ICG@NP or ICG@PM@NP treatments (n = 3). Data were demonstrated as mean ± SD. Statistical analysis was performed via the two-tail Student’s t-testBack to article page
