Dark matter candidates with masses below 10 GeV/c² hold promise, and a new detector, DarkSide-LowMass, is proposed based on the DarkSide-50 detector and progress towards the DarkSide-20k. DarkSide-LowMass is optimized for low-threshold electron-counting measurements, and sensitivity to light dark matter is explored for various potential energy thresholds and background rates. I will present the developments towards low mass dark matter searches with a new detector as well as sensitivity with DarkSide-20k, which is under construction.I also discuss the activity for the medical application, Positron Emission Tomography (PET) scanner, using the same technologies as dark matter searches.
