### Description

Low-background anisotropic scintillators can be reliable detectors to investigate those Dark Matter (DM) candidates inducing just nuclear recoils, through the directionality technique. The directionality is based on the study of the correlation between nuclear recoils direction and Earth motion in the galactic rest frame. In an anisotropic detector, the signal induced by those DM candidates inducing just nuclear recoils is expected to change with a peculiar behavior as a function of the sidereal time. Among the anisotropic scintillators, the ZnWO$_{4}$ has unique features and is an excellent candidate detector. In particular, both the light output and the scintillation pulse shape depend on the impinging direction of heavy particles with respect to the crystal axes; these two features can be independently exploited to study the directionality and to statistically discriminate recoils to gamma/beta radiation (that gives no anisotropic effect). In the talk the developments and the perspectives of the low background ADAMO pioneer experiment to exploit deep underground the directionality approach by using anisotropic ZnWO$_{4}$ scintillators as well as its complementarity to existing positive results will be discussed.
