Nanotechnology helps to sustainably save cleaning agents or to completely dispense with conventional cleaning, thus improving the CO2 balance in many industries. It protects against hazards (chemicals, oil, water, dust and germs such as MRSA) and can be applied in an ecologically optimised way. Since the name "nano" and "ceramic coating" are used synonymously for many surface systems in the market, it is difficult to determine the quality based on the label description for the consumer or business customer. It is advisable to purchase the products from a verified manufacturer, developer or producer. In Germany (made in Germany), these are usually recognized as spin-offs from research institutions.
