Paracellular transport is the movement of substances across an epithelium by passing through the intercellular space between the cells while transcellular transport involves the passage of solutes by a cell through a cell [13]. Physicochemical properties of TiO2 and ZnO The physicochemical properties of nanoparticles that have been identified as important factors in uptake and toxicity include crystal structure, size, surface charge, surface energy, and chemical composition [14]. Crystal structure TiO2 occurs naturally in three crystalline structures: rutile (tetragonal), anatase (tetragonal), and brokite (orthorhombic). Rutile is the most common and stable form of this mineral. ZnO exhibts two main crystalline forms: wurtzite (hexagonal)
