Nanotechnology is the buzzword among international scientific researchers.However,desp te the fancy label,nanoscience isn't something for the future;it's already been used in dozens of products.Products using this technology are now available on ordinary supermarket shelves across China.“Nanoscience and technology has stepped out of the lab and into the society to bring more convenience to people's everyday life,” said Bai Chunlin,President of the Chinese Academy of Sciences (CAS)and chief scientist of the National Center for Nanoscience and Technology.Most people,however,still struggle to identify nano materials.
