Boron Nitride (BN) Nanoparticles
Recently, boron nitride nanoparticles and nanosheets have drawn a lot of attention due to their unique, mechanical, optical, physical and chemical properties. They are regarded as interesting materials for a variety of applications as boron neutron capture therapy agent, antibacterial agents, nanocarrier for drug deliver, solid lubricant, nanofiller reinforcing phase in metallic matrix, catalysts, surface enhanced Raman spectroscopy substrate and polymer matrix composites. They have also found applications as an element of electronic, plasmonic, optoelectronic gas and biological sensor, photodetector, water purifier and magnetic and semiconducting devices. The broad range of applications of boron nitride nanoparticles is due to the combination of chemical, optical and physical properties including high thermal stability, larger interlayer shear force, resistance against oxidization, enhanced adsorbing capacity, low specific density, excellent dispersion stability and transparency with a wide bandgap. There are numerous methods to fabricate boron nitride nanoparticles such as ion-intercalation assisted exfoliations, pulsed laser deposition, pyrolysis and surface segregation-based methods.
