- the device 7 comprises a reactor 8 with a coating chamber 9, in which the door handle 1 is provided rotatably on a rotary element 10, for example in the manner of a rotary plate.
- the door handle 1 is a door handle which is set up to unlock a door by rotating the door handle relative to the door.

- the connection between the coating chamber 9 of the reactor 8 and the container 12 can be interrupted by a valve 13 in the channel 11. Thus, by means of the valve 13, a Flow of the nanoparticles 4 into the coating chamber 9 of the reactor 8 can either be made possible or completely or partially prevented.
- the valve 13 is at least partially opened, so that the nanoparticles 4 get into the reactor 8 and come into contact with the layer 3.
- the nanoparticles 4 are at least partially enclosed in the layer 3 and consequently on the surface to be coated
- the nanoparticles 4 can be generated in the container 12, for example. This can take place, for example, by evaporation, ablation, plasma formation or exfoliation of a solid, liquid or gaseous starting material 14. After the production of the nanoparticles 4, they are conveyed into the reactor 8 via the channel 11 with the valve 13 open at least partially. This can be done, for example, by gravity, a pressure difference and / or by a flow of a carrier gas or a carrier liquid.
- FIG. 2 shows the door handle 1 in a sectional view along the line in FIG. 1 shown section line II-II. The surface 2 of the door handle 1 coated with the layer 3 can be seen here in particular.
- the nanoparticles 4 are at least partially enclosed in the layer 3.
- the nanoparticles 4 have a diameter 5 which can be, for example, 1 nm to 10 nm.
