Water purification with nanotechnology

A cartoon poster about how water can be purified using nanotechnology. Scientists make tiny silver particles, called nano silver. These are used to clean water because they are antibiotics. This means that they kill bacteria, such as E.coli, which causes diseases and sometimes death. You can get plastic water barrels that contain nano silver particles. The nano silver particles combine with the cell walls of the bacteria, and stop them from getting oxygen. In other words, they suffocate the bacteria. If you leave water in the barrel for a few hours, all the harmful bacteria will be killed.
