Laser ablation of Fe 2 B target enriched in 10 B content for boron neutron capture therapy

The technique of laser ablation in liquids is applied to produce Boron-containing nanoparticles from ablation of a Fe 2 B bulk target enriched in 10 B isotope. Laser ablation of the target in liquid isopropanol results in partial disproportionation to free Fe and Boron while nanoparticles of Fe 2 B are also presented. The nanoparticles are magnetic and can be collected using a permanent magnet. The average size of nanoparticles is about 15 nm. The content of 10 B in the generated nanoparticles amounts to 76.9%. The nanoparticles are biocompatible and can be used in boron neutron capture therapy.
