Visualization of the PC70 drug delivery system using PC70-Nile Red (PC70-NR) treatment in zebrafish larvae. (a) Representative images of PC70-NR- or NR-treated zebrafish. Seventy-two hpf larvae were exposed to 1% PC70-NR (containing 200 μg/mL PC70 with 1 ng/mL NR) or 1 ng/mL NR for 2 and 20 h, respectively. Following this, the fish were washed in breeding water for 18 h. Red colouration indicated NR fluorescence. (b) Quantification of NR fluorescence in zebrafish treated with PC70-NR or NR. * p < 0.05, ** p < 0.01. Each experimental group contained 12 fish; error bars indicate SD.
