Boron nanoparticles (BNPs) are attractive nanomaterials for their employment in many applications, such as neutron detection, boron capture therapy, proton therapy and nuclear fusion. Depending on the specific application, 10B or 11B isotopes can be used. Nevertheless, there significant challenges developing suitable BNPs using both conventional chemical synthesis routes dry fabrication techniques. In this study we report directly synthetised water by pulsed Laser Ablation Liquid (PLAL). Nanoparticles of elemental have been generated laser ablation a sintered target MilliQ employing ns pulse. The resulted micro-fragments with hydrogen gas boric acid by-products. Simple washing steps were used to obtain clean water. showed narrow size distribution between 3 4 nm stability was induced thin layer oxide surrounds BNPs. fully characterized structural point view several A discussion reactions during after NPs released solution done.
