Figure 2

Physico-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).
