Nanoparticles have a range of applications. They can be accumulated in ecological biota and delivered to other organisms via food chain. This study investigated trophic transfer of fluorescent nanoparticles, quantum dots (QDs). With bio-imaging technique, we visually and quantitatively proved that quantum dots (QDs) from low-level to high-level organisms in the food chain using intravital multi-photon laser scanning microscope. Bioaccumulation was also observed in the higher trophic levels. This study has implications for safe use of nanoparticles.
