A transport system for dry nanoparticles (18b). According to the invention, the nanoparticles (18b) are magnetized or electrically charged for transportation, a magnetic or electrical field is produced by a field generator (20a, 20) in the transport channel, and the nanoparticles (18b) migrate through the transport channel (12). The nanoparticles can be discharged through a discharge opening (13) which enables dosing to take place. In order to agglomerate the nanoparticles (18b) or to prevent attachment onto the inner wall (26), a coating (27) of the wall can be offset in oscillations by piezo electric actuators (28), the oscillations being transferred to the nanoparticles (18b). The dry nanoparticles can be handled in an advantageous manner due to the transport system, such that the dry nanoparticles need not be treated as a suspension.
