Approximately two billion people worldwide do not have access to safely managed drinking water services, 3.6 billion lack safe sanitation and 2.3 billion lack basic hand-washing facilities, according to the World Bank. The figures are clear: we are facing a water crisis.
This crisis has implications for the health, safety and well-being of millions of people. For example, one of the consequences of a lack of clean water is the spread of infections and deadly diseases such as cholera and dysentery. It also affects food production, leading to hunger in vulnerable communities.
In the framework of World Water Day, we want to explore how nanotechnology can become a key tool to address the problem of global water treatment and management. This science includes technologies that operate at the nanoscale, between 1 and 100 nanometres.
