An assembly for picking and transporting nano-objects, comprises a cassette having first and second components, which are provided with means of mutual assembly and with means for holding the filter. The first and second components define, when the components are in an assembled configuration, a cavity in which the filter is housed and held therein. The means of mutual assembly comprise first clipping means secured to the first component, second clipping means secured to the second component and able to collaborate with the first clipping means so as to clip the two components together. A picking device comprises suction means to which the cassette is able to be removably attached. The first and second clipping means are configured such that they are not accessible from the outside when the components are in the assembled configuration with the cassette fixed to the device.

A filtration assembly for filtering nanoparticles includes a filter having pores that can retain nanoparticles likely to be found in an air flow passing through the filter and a filter support including two parts. A lower base-forming part of the filter support includes a peripheral bearing surface on which the filter can rest. An upper ring-shaped part of the filter support is designed to be mounted around the bearing surface of the base. By mounting the ring around the bearing surface of the base it is possible to tension the filter radially to the direction of mounting. The mounting clearance between the ring and the bearing surface of the base is dimensioned such as to maintain the filter resting on the bearing surface under mechanical stress by means of pinching, in a direction radial to the mounting direction.

A device for sampling and transporting nano-objects for analysis thereof. A cassette portion of the device includes two parts with mutual assembly mechanisms between them including a clipping mechanism configured not to be accessible from outside in assembled position of the parts. Therefore, any inopportune opening of the cassette and thus extraction of the sampling filter accommodated in the cassette somewhere else than the place intended for the analysis are avoided.
