With the growth of nanodosimetry, many applications would benefit from the development of portable nanodosimeters, $i.e.$, compact and light devices that quantify the energy released by ionizing radiation within nanometric volumes. A possibility could be the use of quantum dots (QDs) as active material, since their size is comparable with those of the most probable radio-sensitive volumes of biological systems. Since the development of such devices depends on a deep understanding of the physical interaction mechanisms between ionizing radiation and QDs, our preliminary work aims to investigate the change in the QD optical properties between the pre- and post-irradiation treatment.
