After a brief overview on direct search experiments for dark matter particles I will concentrate on axionic dark matter. Axions were originally introduced to solve the strong CP problem, but they are also a very interesting dark matter candidate. I will decribe recent theoretical ideas to use S/N/S Josephson junctions as suitable axion detectors, and discuss a candidate signal of unknown origin observed by an experimental group in Grenoble, which interpreted in this way would point to an axion mass of 0.11 meV.
