Boron nitride nanosheets (BN NSs), a novel material with great potential in biomedical applications, have attracted great attention due to its extraordinary properties. A crucial issue is the toxicity of BN NSs, which depends greatly on various factors, including size. The size may affect viability of cells due to the interactions between BN NSs and cell membranes. In this study, two kinds of silkworms (qiufeng × baiyu, Nistari 7019) were used as models to investigate the toxicity of BN NSs with different sizes (BN NSs-1: thickness of 41.5 nm, average diameter of about 200 nm; BN NSs-2: thickness of 48.2 nm, average diameter of about 500 nm) from the levels of animal entirety (silkworm mortality, silkworm growth, cocoons) and tissues. The results show that exposure to different sized BN NSs causes no obvious adverse effects on the growth or tissues of silkworm. This study has performed size-dependent in vivo toxicity evaluation of BN NSs and provided safety information to enrich the database for better application of BN NSs. Further studies should be carried out to discover the biosafety of diverse sizes and shapes BN NSs.

Diffuse Ring

Boron nitride derived from polymer precursors is of great interest for applications such as fibers, coatings and novel forms such as aerogels. The BN is prepared by the polymerization of functionalized borazine and thermal treatment in nitrogen at 1200°C. The BN powders obtained by this route are invariably trubostratic wherein the sheets of hexagonal BN are randomly oriented to yield the so-called turbostratic modification. Fib 1a and 1b show images of BN powder with the corresponding diffraction pattern in fig. 1c. The (0002) reflection from BN is seen as a diffuse ring with occational spots that come from crystals of BN such as those shown in fig. 1b. The (0002) lattice fringes of BN seen in these powders are the most characteristic indication of the crystallinity of the BN.

Microstructure Of The Material

The allotropes of boron nitride include two sp2-bonded phases with hexagonal and rhombohedral structures (hBN and rBN) and two sp3-bonded phases with cubic (zincblende) and hexagonal (wurtzitic) structures (cBN and wBN) (Fig. 1). Although cBN is synthesized in bulk form by conversion of hBN at high temperatures and pressures, low-pressure synthesis of cBN as a thin film is more difficult and succeeds only when the growing film is simultaneously irradiated with a high flux of ions. Only sp2-bonded material, which generally has a disordered, turbostratic microstructure (tBN), will form in the absence of ion-irradiation. The mechanistic role of the irradiation is not well understood, but recent work suggests that ion-induced compressive film stress may induce the transformation to cBN.Typically, BN films are deposited at temperatures less than 1000°C, a regime for which the structure of the sp2-bonded precursor material dictates the phase and microstructure of the material that forms from conventional (bulk) high pressure treatment.
