Experimental observations and theoretical arguments have pointed out that a large part of the Universe is composed by Dark Matter particles. This motivates experimental efforts to investigate the direct detection of these particles with detectors placed in underground laboratories. In this paper a short review of some used techniques will be presented. Particular care will be given to the results obtained by the DAMA/LIBRA set-up. In addition, experimental and theoretical uncertainties and their implications in the interpretation and comparison of different kinds of results will be shortly addressed.
