Background: In boron neutron capture therapy (BNCT), the intravenous administration of boron-containing compounds such as boronophenylalanine (BPA) and borocaptate sodium (BSH) is followed by irradiation with thermal neutrons. In the present study, we determined whether a boron-rich boron carbide (B4C) nanoparticle could be used for BNCT. Methods: B4C … · The properties of boron compounds vary greatly. Properties of selected boron compounds follow. Borax comes in hard, odourless crystals, granules or powder. It has a melting point of 75°C and boils at 320°C. ... Boron can be transported as particles released into the atmosphere or as dissolved compounds in natural waters.

Boron-10, one of the naturally occurring isotopes of boron, is a good absorber of neutrons and is used in the control rods of nuclear reactors, as a radiation shield and as a neutron detector. Boron filaments are used in the aerospace industry because of their high-strength and lightweight. Boron forms several commercially important compounds. · [13,14]. Since a concentrated amount of boron is required in a tumor cell for high effective BNCT, the application of B4C particles with numerous boron atoms may improve the efficiency of this therapy. The intratumoral application of such boron-rich compounds may eradicate BNCT-resistant tumor cells that do not take up BPA.
