Uptake and accumulation of orally deliverable 7 PABA nanomaterials. (A) Uptake and accumulation of nanoparticles in eye, leg and wing imaginal discs, and (B) adult brain were shown. (C) Heat and intensity map representing larval discs specific uptake in complex adult tissues, eyes, halters, legs and brains of 7 PABA nanoparticles were presented. The different colour represents intensity of nanoparticles uptake (noted at the top). Each column represents mean values from six different experiments. The whitish blue refers to the lowest percentage of uptake (10%) and red refers to the highest accumulation (100%).
