A plasma containing submicron-sized particles is an interesting object from both basic plasma physics and plasma technology point of view. The density of the nanoparticles strongly depends on the ability of the discharge to confine particles and its interplay with the repelling forces between the particles. To diagnose the plasma, information on the size of the particle, their size- and spatial distribution, and their density are needed. With all this information dust density waves (DDW) can be used to diagnose the plasma. The advantage of the DDW diagnostic is that it is noninvasive and the waves can easily be studied by means of video microscopy. We discuss several findings and compare with results from other diagnostics like microwave interferometry and electrostatic probes.
