A low-temperature technology was developed for producing a nanocomposite based on poly (lactic-co-glycolic acid) and zinc oxide nanoparticles (ZnO-NPs), synthesized by laser ablation. Nanocomposites were created containing 0.001, 0.01, 0.1% of with rod-like morphology size 40-70 nm. The surface the films from obtained nanomaterial uniform, without significant defects. Clustering ZnO-NPs in PLGA matrix noted, which increased an increase concentration dopant polymer. resulting capable...
Microbial antibiotic resistance is an important global world health problem. Recently, interest in nanoparticles (NPs) of silver oxides as compounds with antibacterial potential has significantly increased. From a practical point view, composites oxide NPs and biocompatible material are interest. A borosiloxane (BS) can be used one such material. composite combining BS been synthesized. Composites containing have adjustable viscoelastic properties. The synthesized by laser ablation size ~65...
An electrospark technology has been developed for obtaining a colloidal solution containing nanosized amorphous carbon. The advantages of the are its low cost and high performance. carbon is highly stable. coatings on basis nanostructured. They characterized by adhesion hydrophobicity. It was found that propagation microorganisms significantly hindered. At same time, eukaryotic animal cells grow develop coatings, as well nitinol medical alloy. use available, cheap non-toxic nanomaterial...
The evolution of the size distribution nanoparticles depending on concentration in a colloidal solution is investigated. formation new stable distributions shifted relative to initial directly related processes agglomeration nanoparticles. Using successive two-fold dilutions by 2–32 times, it was shown that maximum nanoparticle shifts toward smaller sizes with decrease nanoparticles, both for number and mass Thus, dilutions, individual increases, while particles one aggregate decreases. A...
A method for obtaining a stable colloidal solution of silver oxide nanoparticles has been developed using laser ablation. The allows one to obtain with monomodal size distribution and concentration more than 108 per mL. On the basis obtained PLGA polymer, nanocomposite material was manufactured. manufacturing technology without significant defects. Nanoparticles are not evenly distributed in form domains composite. Reactive oxygen species (hydrogen peroxide hydroxyl radical) intensively...
Development of eco-friendly and biodegradable package materials is an important goal modern science international industry. Poly(lactic)-co-glycolic acid (PLGA) suitable for this purpose. However, biocompatible may be contaminated with bacteria. This problem solved by the addition metal oxides nanoparticles (NPs) antibacterial properties. Although NPs often show cytotoxicity against plant mammalian cells, a new nanocomposite based on PLGA aluminum oxide (Al2O3) has been developed. The...
Polarization of femtosecond laser radiation influence on the windings ellipsoidal silver nanoparticles and their orientation in zinc oxide sol-gel films was studied, which caused appearance dichroism irradiation field. Unlike silver-containing glasses, where this mechanism discovered, it has hardly been studied thin before. Femtosecond pulses with a high degree repetition linear polarization controlled shape, size oriented horizontally along across direction. For to occur, is necessary...
