Аннотация: We report on a model of an organic solar cell in which a photosensitive layer doped with plasmon nanoparticles acts as not only an absorbing element but also a mirror involved in the formation of the Tamm plasmon polariton. It is shown that such solar cells can be fabricated without metal contacts, thus avoiding undesired losses in the system. Methods for an additional increase in the integral absorption by applying metal or dielectric mirrors to the lower boundary of the photonic crystal are proposed. It has been found that the integral absorption in the active layer can be increased by15%compared to classical optimized planar solar cells.

Аннотация: The effect of magnetic nanoparticles coated with arabinogalactan on the viability of Ehrlich ascites carcinoma (EAC) cells was studied. The nanoparticles were studied by transmission electron microscopy, Mossbauer spectroscopy, IR spectroscopy, and ferromagnetic resonance. A correlation between the proportion of dead EAC cells in suspension and the intensity of the EPR signal of dinitrosyl iron complexes was found. This result may be due to the presence of NO molecules.

Аннотация: We have established numerically the physical pattern and conditions for formation of nanosized bubbles in aqueous medium around biocompatible plasmonic nanoparticles (NPs) selectively bound to the membrane of the malignant cells by means of DNA-aptamers under the action of picosecond laser radiation. The results obtained are based on the finite volume method and hydrodynamic models underlying the ANSYS Fluent package with extended capabilities. We have found the main features and previously unknown dominant factors of the damage effect on the cell membrane at the moment of the bubble nucleation around the plasmonic NPs of different types taking into account the influence of the closely located membrane. Information on the kinetics of spatial distribution of pressure, temperature and the relative proportion of vapor in the 'nanoparticle-membrane-medium' system have been obtained. The attention is drawn to the advantages of using biocompatible, perfectly absorbing core–shell plasmonic NPs for anti-tumor therapy characterized by an increased mechanical effect on malignant cell membranes at lower laser radiation intensity and the spectral position of their plasmon resonance (λ = 700 nm) in the hemoglobin transparency range. This ensures penetration of laser radiation deep into tissues. The paper is provided with an extensive review of key publications and the state-of-art in this area.

Аннотация: This paper reports studies of thin films of nickel oxide obtained by the extraction–pyrolysis method on glass and quartz substrates at temperatures of 380–600°C. The films have been characterized by atomic force microscopy and X-ray diffraction. It is shown that amorphous and crystalline nickel oxide films are formed on the glass. The grain size depends on the annealing temperature, while increased annealing temperatures lead to recrystallization and a decrease in the grain size in NiO films from 130 to 35 nm.

Effects of modified magnetite nanoparticles on bacterial cells and enzyme reactions / L. S. Bondarenko, E. S. Kovel, K. A.

Аннотация: Current paper presents biological effects of magnetite nanoparticles (MNPs). Analyzing effects of MNP’ characteristics (zeta-potential and hydrodynamic diameters) on bacteria and their enzyme reactions was the main focus. Photobacterium phosphoreum and bacterial enzymatic reactions were chosen as bioassays. Three types of MNPs were under study: bare Fe3O4, Fe3O4 modified with 3-aminopropyltriethoxysilane (Fe3O4/APTES), and humic acids (Fe3O4/HA). Effects of the MNPs were studied at a low concentration range (< 2 mg/L) and attributed to availability and oxidative activity of Fe3+, high negative surface charge, and low hydrodynamic diameter of Fe3O4/HA, as well as higher Fe3+ content in suspensions of Fe3O4/HA. Low-concentration suspensions of bare Fe3O4 provided inhibitory effects in both bacterial and enzymatic bioassays, whereas the MNPs with modified surface (Fe3O4/APTES and Fe3O4/HA) did not affect the enzymatic activity. Under oxidative stress (i.e., in the solutions of model oxidizer, 1,4-benzoquinone), MNPs did not reveal antioxidant activity, moreover, Fe3O4/HA demonstrated additional inhibitory activity. The study contributes to the deeper understanding of a role of humic substances and silica in biogeochemical cycling of iron. Bioluminescence assays, cellular and enzymatic, can serve as convenient tools to evaluate bioavailability of Fe3+ in natural dispersions of iron-containing nanoparticles, e.g., magnetite, ferrihydrite, etc.

Аннотация: Biomedical engineering is the most promising field for the application of ferrogels as scaffolds for cell culturing in regenerative medicine, targeted drug delivery, and biosensorics. This study is focused on the contribution of ferric-oxide magnetic nanoparticles (MNPs) to the biocompatibility of ferrogels with human dermal fibroblasts. The results of experiments with polyacrylamide gels filled with MNPs are presented. These experiments demonstrate that, regardless of the mechanical and electrical characteristics of ferrogels, MNPs have a significant effect on the biological activity of cells.
