Fig. 1From: Vasomotor function in rat arteries after ex vivo and intragastric exposure to food-grade titanium dioxide and vegetable carbon particlesTEM images of E153 and E171. Dry particle size and morphology of E153 and E171 was determined by TEM images. (a1) and (a2) are images of E171, magnification 5800×. Three size groups of E171 particles were observed in the pictures. (b) and (c) are images of E153, magnification 5800× (b) and 44,000× (c). Two size groups of particles were observed for E153. Scale bars are 500 nmBack to article page
