Hexagonal boron nitride at low temperatures: controlled synthesis and mechanism

Analytical Chemistry Letters, Год журнала: 2025, Номер unknown, С. 1 - 10

As a structural counterpart of graphite, hexagonal boron nitride (hBN) exhibits distinct advantages over bulk hBN, including high thermal conductivity and electrical insulation, exceptional strength, low friction coefficient as well elastic modulus, which make it unique material for wide variety applications. Despite this, the controlled scalable synthesis maintaining stoichiometric balance between nitrogen atoms during crystal growth has remained daunting challenge in last few decades. Herein, simple yet efficient method was employed to optimize heat-treatment urea, thiourea, boric acid at melting temperatures. This resulted hBNs very temperatures single step, under normal atmospheric conditions. The FESEM images hBN produced from both urea thiourea showed formation layered structure nitrides. magnified TEM clearly depicted lattice fringes within hBN. overall results confirmed that V-shape might have helped produce large scale, bypassing use substrates, temperature or pressure.

The biodegradation of hexagonal boron nitride (h-BN) nanomaterials by neutrophils was investigated. After incubation for 36 h, h-BN nanosheets are taken up neutrophils, and their structure is highly disrupted, as observed via high-resolution transmission electron microscopy (HR-TEM) confocal Raman imaging. Among the three degradation pathways, release neutrophil extracellular traps from dominant, with myeloperoxidase (MPO) playing an important role. Molecular dynamics simulations show that MPO spontaneously attach onto surface, leverage active sites to form favorable contacts initiate degradation. Hypochlorite produced responsible With assistance hypochlorite, B–O N–O bonds formed on h-BN, along B–N bond breakage ionic nitrogen based byproduct identification first-principle calculations. Additionally, significantly degraded into small pieces, particle concentration a size 0–100 nm increases 58.7% after Following degradation, induce significant hemolysis red blood cells, exhibit higher cytotoxicity against epithelial cells. Our findings highlight importance considering its safe application, demonstrate actual risk in biological natural environments.

Boron nitride nanosheets, quantum dots, and dots: Synthesis, properties, and biomedical applications

APL Materials, Год журнала: 2025, Номер 13(4)

Опубликована: Апрель 1, 2025

This review examines three aspects of hexagonal boron nitride (h-BN) nanomaterials: properties, synthesis methods, and biomedical applications. We focus the scope on types h-BN nanostructures: nanosheets (BNNSs, few-layered h-BN, larger than ∼100 nm in lateral dimensions), quantum dots (BN QDs, smaller ∼10 all dimensions, with inherent excitation-dependent fluorescence), dots, wide bandgap without noise fluorescence). The methods BNNSs, BN are summarized top-down bottom-up approaches. Future research should scalability quality products, which essential for reproducible Regarding applications, BNNSs were used as nanocarriers drug delivery, mechanical reinforcements (bone tissue engineering), antibacterial QDs still limited non-specific bioimaging small dimension to construct high-brightness probes (HBPs) gene sequence detections inside cells. To differentiate from other two-dimensional materials, future applications using unique properties nanostructures, such piezoelectricity, neutron capture therapy (BNCT), their electrically insulating optically transparent nature. Examples would be combining BNCT chemo delivery form HBPs enhanced fluorescence by preventing quenching dots.
