Figure 2From: Sub-cellular internalization and organ specific oral delivery of PABA nanoparticles by side chain variationPhysico-chemical properties and microscopic views of seven PABA anomaterials. elative Uptake of several nanomaterials in insect (Drosophila S2) and human tumour cells (HeLa) were shown. The differences in chemical structure, shape and surface texture of nanomaterials leads to a variation in cell uptake. Scale- 250 nm (SEM), 50 μm (cells).Back to article page
