Abstract The NEMO experiment investigates the neutrinoless double beta decay. The NEMO-3 detector is collecting data in the Frejus Underground Laboratory. The goal of the SuperNEMO detector is to reach a sensitivity of the order of 10 26 year on the half-life of the β β 0 ν process. The chosen isotopes for the future detector are 82Se and 150Nd, because of the reduced background. The collaboration has started a 3-year R& D development on all components: tracking detector, calorimeter, source enrichment and purification and radiopurity measurements.
