Boron nitride nanotubes (BNNTs) have been increasingly investigated for use in a wide range of applications due to their unique physicochemical properties including high hydrophobicity, heat and electrical insulation, resistance to oxidation, and hydrogen storage capacity. They are also valued for their possible medical and biomedical applications including drug delivery, use in biomaterials, and neutron capture therapy. In this review, BNNT synthesis methods and the surface modification strategies are first discussed, and then their toxicity and application studies are summarized. Finally, a perspective for the future use of these novel materials is discussed.

The Stability

The hydrogen-rich compound ( H 2)n CH 4 (for n = 1, 2, 3, 4) or for short ( H 2)n M is one of the most promising hydrogen storage materials. The ( H 2)4 M molecule is the best hydrogen-rich compound among the ( H 2)n M structures and it can reach the hydrogen storage capacity of 50.2 wt.%. However, the ( H 2)n M always requires a certain pressure to remain stable. In this work, we first investigated the binding energy of the different structures in ( H 2)n M and energy barrier of H 2 rotation under different pressures at ambient temperature, applying ab initio methods based on van der Waals density functional (vdW-DF). It was found that at 0 GPa, the ( H 2)n M is not stable, while at 5.8 GPa, the stability of ( H 2)n M strongly depends on its structure. We further investigate the Raman spectra of ( H 2)n M structures at 5.8 GPa and found the results were consistent with experiments. Excitingly, we found that boron nitride nanotubes (BNNTs) and graphite and hexagonal boron nitride ( h - BN ) can be used to store ( H 2)4 M , which give insights into hydrogen storage practical applications.

An efficient chemical vapor deposition (CVD) method was successfully utilized to synthesize boron nitride nanotubes (BNNTs), where Ammonium boron trifluoride (NH3BF[Formula: see text] and MgCl2 were employed as the novel single-source precursor and the promoter, respectively. The as-obtained BNNTs displayed a collapsed structure with the average diameter of 15[Formula: see text]nm and lengths up to tens of micrometers, named as collapsed BNNTs. They exhibited a reproducible hydrogen storage capacity of 2.63[Formula: see text]wt.% under 10 MPa and at ambient temperature. Moreover, they showed an high storage cycling stability due to the excellent chemical and structural stability.

Straightforward Approach

In recent years have seen a surge of increased interest in the exfoliation of boron nitride (h-BN) due to its exciting electrical, thermal, photonics mechanical properties and sensing. Several approach to have emerged describing the exfoliation, functionalized and solubilization of h-BN. In this study, we report on a straightforward approach to modify the surface and its application as a new type of biomedical applications. The prepared product is structurally characterized by FTIR spectroscopy, field emission (FESEM), TGA technique, XPS spectrum, and BET surface area measurements. Nano- composites were immobilized on electrodes to detect the glucose, L-cysteine in buffer medium by cyclic voltammetry (CV), square wave voltammetry (SWV), and impedance spectroscopic (EIS). potential application of the covalent functionalization, cheap precursors, biodegradability and multifunctionality of high-performance composites boron nitride, they could be used for a wide range of the future biomedical applications.

This paper reports on two examples of biomedical applications of ceramic nanoparticles. Thanks to their physical and chemical inertia, barium titanate nanoparticles and boron nitride nanotubes have been proved to have an optimal in vitro biocompatibility, even at high concentrations. Barium titanate nanoparticles-doxorubicin composites are successfully internalized by cancer cells, and allow for a considerable enhancement of drug up-take. Conversely, boron nitride nanotubes are explored as “nanotransducers”, thanks to their excellent piezoelectric properties. These two examples encourage further investigations and applications in biology and medicine of ceramic nanomaterials, that exhibit interesting advantages respect to traditional materials.
