Nanoparticles (NPs) have a great potential as nanosized drug-delivery carriers. Such systems must safely deliver the drug to site of tumor without leakage, effectively penetrate inside cancer cells, and provide intracellular release. Herein we developed an original simple method aimed at fabrication spherical boron nitride NPs (BNNPs), 100–200 nm in diameter, with peculiar petal-like surfaces via chemical vapor deposition. structures were found be able absorb large amount antitumor...
Silver is the most famous bactericidal element known from ancient times. Its antibacterial and antifungal effects are typically associated with Ag ionization concentration of Ag+ ions in a bacterial culture. Herein we thoroughly studied influence surface topography roughness on rate ion release. We considered two types biocompatible bioactive TiCaPCON-Ag films 1 2 at. % nine Ti surfaces an average varying range 5.4 × 10-2 to 12.6 μm different topographic features obtained through polishing,...
Enhanced incorporation of hydroxyapatite nanoparticles in porous titania coating formed by plasma electrolytic oxidation significantly increases surface osteogenic activity.
We have developed advanced folate bonded to boron nitride (BN) nanocarriers with a high potential for targeted drug delivery. The folic acid (FA) molecules were successfully conjugated BN nanoparticles (BNNPs) in three consecutive stages: (i) FA preactivation by N,N′-dicyclohexylcarbodiimide (DCC), (ii) BNNP modification AgNPs and their further NH2-functionalization l-cysteine, (iii) final conjugation of activated modified BNNPs. To shed light on the FA-BNNPs binding mechanism, detailed...
Herein we study the effect of doxorubicin-loaded BN nanoparticles (DOX-BNNPs) on cell lines that differ in multidrug resistance (MDR), namely KB-3-1 and MDR KB-8-5 cervical carcinoma lines, K562 i-S9 leukemia lines. We aim at revealing possible differences cytotoxic free DOX DOX-BNNP nanoconjugates these types cells. The spectrophotometric measurements have demonstrated maximum amount DOX-BNNPs is obtained after saturation alkaline solution (pH 8.4), indicating high efficiency BNNPs with...
Boron nitride nanostructures (nanotubes, graphene-like petals, and columnar porous flakes) grew in reactions of alkali alkaline earth borates with ammonia.
It is very important to prevent bacterial colonization at the early postoperative stages. There are four major strategies and their corresponding types of antibacterial surfaces specifically designed fight infection: bactericide release, anti-adhesion, pH-sensitive, contact-killing. Herein, we aimed determining efficiency different bactericidal ions revealing possible contribution surface microgalvanic effects arising from a potential difference on heterogeneous surfaces. We considered five...
BN/Ag hybrid nanomaterials (HNMs) and their possible applications as novel active catalysts antibacterial agents are investigated. nanoparticle (NP) hybrids were fabricated using two methods: (i) chemical vapour deposition (CVD) of BN NPs in the presence Ag vapours, (ii) ultraviolet (UV) decomposition AgNO 3 a suspension NPs. The microstructures studied by high-resolution transmission electron microscopy (HRTEM), high-angular dark field scanning TEM imaging paired with energy dispersion...
A rich variety of hollow and solid (without internal spaces) spherical boron oxynitride nanoparticles (BNO-NPs) with smooth or petalled surfaces were synthesized during a oxide-assisted chemical vapour deposition (BOCVD) process. Diverse BNO-NPs obtained while utilizing different precursors, gas flow rates synthesis temperatures in the range 1200–1430 °C. The BNO-NP morphologies, atomic structures spatially-resolved compositions studied by scanning (SEM) transmission electron microscopy...
