摘要：Over the past decade, products based on nanotechnology and nanomaterials have created a fast-growing consumer market (http://www.nanotechproject. org/). Over 1827 consumer products have reached the supermarkets and millions of customers. At least about 39 different nanomaterials were found in these products, such as those made from metals (Ag, Ti, Zn, Au), metal oxides (TiO_2, Fe_2 O_3, ZnO), carbonaceous (carbon, CNTs, fullerenes, graphene) and silica. The majority of nanotechnology products are usually used in healthcare and fitness, home and garden, automotive, appliances, coatings, electronics, foods and beverages areas. The Future Markets (2012) reported that the worldwide nanomaterial production will be over 340,000 tons by the end of 2016. The production of TiO_2 nanoparticles tops all nanomaterials, followed by ZnO, CNTs and Ag nanoparticles (http://www.marketresearch.com/ Future-Markets-Inc-v3760/ Global- Nanomaterials-Production-volumesrevenues- 6916724/).
