Query: Laser ablation of Fe$_2$B target enriched in 10B content for boron
  neutron capture therapy   The technique of laser ablation in liquids is applied to produce of
Boron-containing nanoparticles from ablation of a Fe$_2$B bulk target enriched
in 10B 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. Nanoparticles are magnetic and can be collected using a
permanent magnet. Average size of nanoparticles is of 15 nm. The content of 10B
in generated nanoparticles amounts to 76,9 %. Nanoparticles are biocompatible
and can be used in Boron Neutron Capture Therapy.
