Fluorescence optical imaging of BALB/c mice bearing Colon26 tumors. (A) Control mouse, no drug, black circle indicates location of tumor (B) 24 hours post-injection of HPPH (0.47 µmol/kg) and (C) 24 hours post-injection of HPPH post-loaded PAA nanoparticles (0.47 µmol/kg). The false-colored images are scaled to the same intensity range and show representative images with fluorescence intensity closest to the average values. The ROI over the tumor for measuring fluorescence intensity is indicated in A. The bar graph shows the fluorescence intensity in the ROI (average ± standard deviation of three samples).
