LiquidO is a new neutrino detection technology which uses opaque liquid scintillator (LS), like milk or paraffine, with a very short scattering length and an intermediate absorption length, contrary to the traditional approach that uses transparent LS volumes,  with scattering lengths of up to tens of metres, as neutrino targets surrounded by sensitive  sensors that collect light. Reducing the scattering length down to the scale of millimeters causes the light to be con fined to a few cm volume near its creation point. To extract the light a lattice of wavelength-shifting  fibres runs through the scintillator. The LiquidO technique provides high-resolution imaging that enables highly efficient identi fication of individual particles event-by-event. Additionally, the exploitation of an opaque medium gives LiquidO natural affinity for using dopants at unprecedent levels. A small prototype called "micro-LiquidO" was recently built and tested with a 1MeV monochromatic electron beam, validating the basic principles behind the new paradigm. The possible contribution of the Ciemat to this project will be also presented in this talk.
