Mode Vibration

We found that oxidized Cu nanoparticles can catalyze the growth of boron nitride nanotubes from borazine via plasma-assisted chemical vapor deposition. The Raman spectra suggest that the formation of thin-walled nanotubes show a radial breathing mode vibration. The presence of oxygen in the plasma environment was necessary for the growth of the nanotubes, and a part of the nanotubes had a core shell structure with a cupper species inside it. In atomic resolution transmission electron microscope (TEM) images, Cu2O was found at the interface between the Cu-core and turbostratic BN-shell. The growth mechanism seemed different from that of carbon nanotube core-shell structures. Therefore, we pointed out the important role of the dynamic morphological change in the Cu2O-Cu system.

First Time

While in the last years applications of carbon nanotubes in the field of biotechnology have been largely proposed, biomedical applications of boron nitride nanotubes (BNNTs) are yet totally unexplored. BNNTs have very interesting physical properties that should be exploited in the biomedical field. At this date, studies on their biocompatibility are completely missing and the first issue behind this investigation is the dispersion of BNNTs in aqueous solutions. In this paper the authors propose, for the first time, a technique for obtaining BNNT stable dispersions suitable for biological applications, based on polyethyleneimine (PEI) water solutions. Based on authors' knowledge, in vitro testing performed on human neuroblastoma cell line (SH-SY5Y) is the first study of interaction between BNNTs and living material. Experimental results showed a satisfactory cell viability up to a concentration of 5.0 μg/ml PEI-BNNTs in the cell culture medium.
