This Chapter presents results demonstrating an application of a nanocrystalline coating in
industry. First of all, it considers an application of a nanostructured coating for increasing servicing life
of a tool and for the fabrication of site of various devices, for example, a sensor. An application of a
nanomaterial in a biotechnology (including an artificial collagen), a nanofiltering for a water
purification are considered.
Keywords: Industry, biosensor, bionanotechnology, CNT, cancer cell, CWCNT-polymer.
