Beneficial features of biocompatible high-capacity UiO-66 nanoparticles, mesoporous SiO2, and folate-conjugated pluronic F127 were combined to prepare the core-shell UiO-66@SiO2/F127-FA drug delivery carrier for targeted cellular uptake in cancer treatment. UiO-66-NH2 nanoparticles with a narrow size shape distribution used form series MOF@SiO2 structures. The duration silanization was varied change thickness SiO2 shell, revealing nonlinear dependence that attributed silicon penetration into...
A superconductor–ferromagnet–superconductor Josephson junction based on a single segmented nanowire has been prepared using CNC electrochemical system.
The single-pass one-step method for printing conductive silver tracks on a glass surface, using the laser-induced forward transfer (LIFT) technique, was proposed, providing unique opportunity high-throughput of surface micro- and nanostructures with high electrical conductivity positioning accuracy. This developed via our multi-parametric research, resulting in selection optimal material, laser irradiation, conditions. Optical, scanning transmission electron, atomic force microscopy methods,...
Fibrin is a well-known tool in tissue engineering, but the structure of its modifications created to improve properties remains undiscussed despite their importance,<italic>e.g.</italic>in designing biomaterials that ensure cell migration and lumenogenesis.
We report the successful inactivation of P. aeruginosa strain by femtosecond infrared (IR) laser radiation at resonant wavelengths 3.15 μm and 6.04 μm, chosen due to presence characteristic molecular vibrations in main structural elements bacterial cells these spectral ranges: amide groups proteins (1500-1700 cm-1), C-H membrane lipids (2800-3000 cm-1). The underlying bactericidal changes were revealed stationary Fourier-transform IR spectroscopy, with peaks parameters being obtained...
In this paper, we report the study of low-voltage locally enhanced electric field treatment (LEEFT) E. coli bacteria via TEM analysis and FT-IR Raman spectrometry. The formation pores was confirmed by TEM, which revealed membrane rupture along with precipitates in cell volume, photoluminescence spectra propidium iodide dye. LEEFT results alternation DNA RNA structure, indicated change its α-helical β-helical forms, decrease narrowing nucleic acids-related IR peaks. Membrane damage is...
Polyacrylonitrile and polyheteroarylenes, such as polybenzimidazole (PBI) a polymer of intrinsic microporosity (PIM-1), have been employed to prepare nanoporous electrospun carbon nanofiber (CNF)-based materials for high-temperature proton-exchange (or polymer-electrolyte) membrane (HT-PEM) fuel cells. The CNF mats are obtained by Nanospider (needle-free) electrospinning method from solution followed pyrolysis at 1500 °C form self-supporting with micropores (D < 2 nm) mesopores 2–50 nm)....
Microstructural and electrical properties of PZT (lead zirconate titanate) thin films prepared by sol-gel techniques at annealing temperatures in the range from 550°C to 900°C are studied. Perovskite (Pe) grain nucleation film starts but not completes 550°C. Along with formation round Pe (111) grains on Pt interface, contains small pyrochlore (Py) grains. Films annealed higher than 600°C demonstrate column structure grains, amount Py inclusions reduces temperature practically disappears...
Nanosystems for targeted delivery and remote-controlled release of therapeutic agents has become a top priority in pharmaceutical science drug development recent decades. Application low frequency magnetic field (LFMF) as an external stimulus opens up opportunities to trigger the encapsulated bioactive substances with high locality penetration ability without heating biological tissue vivo. Therefore, novel microencapsulated formulations sensitive LFMF is paramount importance. Here, we...
