Definition of nanotechnology
> Nanotechnology is the investigation, application, and production of structures, molecular materials, and systems with a dimensionor production tolerance of less than 100 nanometres. > The minute scale of the system components alone enables the realisation of new functionalities and properties for improving existing products andapplications or developing new ones.

Nanotechnology in nature
> Nanotechnologists hold living nature dear to their hearts. In the four billion years of its existence, nature has created someastounding solutions to the problems it has encountered. > One typical feature: life structures its matter down to the finest detail, right down to the level of the atom. This is what nanotechnologistsalso aim to do.

> Mimolette is a product of Flanders and the tiny holes in the surface gives away the cheese’s secret: it is inhabited! The producers recognise that the activity of themites improve the aroma of Mimolette cheese. The mites are about a tenth of a millimetre in size. The ESEM (Environmental Scanning Electron Microscope), a special scanning electron microscope, canview even living mites. > Like other living things, mites are also composed of cells. The scale of the cell is the micrometer. > A cell is equipped with highly complex machinery. An important componentof this machinery is represented by the ribosomes, which produce all possible protein molecules according to the specifications of the genetic material DNA. The first fruits of this type ofnanobiotechnology research have already been harvested in the form of new medications capable of blocking bacterial ribosomes
