Colloid Interface Sci. 363, 1–24 (2011) Nanotechnology offers potential benefits to many areas of the food industry including (clockwise from top left) agriculture, food processing, food packaging and the nutritional aspects of food. Of these areas, applications of nanotechnology in food packaging are nearest to the market. 9 Colloid Interface Sci. 363, 1–24 (2011)

Our current knowledge of particle-induced lung tumors in experimental animals can be summarized by stating that all inhaled particles, fibrous and nonfibrous, are likely to induce lung tumors in rats, provided that these particles are (i) inhaled chronically or instilled intratracheally at sufficiently high dose, (ii) respirable to the rat and (iii) highly durable. As we have discussed in this review, the retained lung burden leading to lung tumors can differ for different particles and, apart from dose, greatly depends on particle properties such as surface area and chemistry, cytotoxicity and size/dimensions (Table II)

(1-100 nm) particles derived from transition metals, silver, copper, aluminum, silicon, carbon and metal oxides [...] can easily cross the blood-brain barrier (BBB) and/or produce damage to the barrier integrity by altering endothelial cell membrane permeability [… and] induce brain edema formation Evans Blue Acta Neurochir Suppl. 106 (2010): 359-364
