Formation and stabilization of gold and silver clusters and nanoparticles in mordenites

Pestryakov A., Bogdanchikova N., Tuzovskaya I., Avalos M., Farías M.H., Tomsk Polytechnic University, RU

Supporting silver and gold on mordenites by ion-exchange method with further reduction with H2 leads to formation of neutral and charged metal clusters inside zeolite channels as well as metal nanoparticles on external surface of [...]

Synthesis of Nanocrystalline VOx/MgO Aerogels and Their Application for Destructive Adsorption of CF2Cl2

Ilyina E.V., Mishakov I.V., Vedyagin A.A., Bedilo A.F., Klabunde K.J., Boreskov Institute of Catalysis, RU

Nanocrystalline VOx/MgO is extensively studied as a potential catalyst and adsorbent. In this commutation we shall report further advances to the recently developed method for synthesis of binary VOx/MgO aerogels by hydrolysis of the V [...]

Synthesis of Sulfated and Carbon-Coated Al2O3 Aerogels and Their Activity in Dehydrochlorination of 1-Chlorobutane and (2-Chloroethyl)ethyl Sulfide

Bedilo A.F., Volodin A.M., Klabunde K.J., Boreskov Institute of Catalysis, RU

Alumina is widely used as a sorbent and catalyst support. These applications typically require high surface area, stability in the used environment and often the presence of specific groups on the surface. Many of these [...]

Evaluation of Tools for Nanoparticles-modulated Hyperthermia by Atomic Force Microscopy

Reshetov I.V., Chissov V.I., Sukharev S.S., Matorin O.V., Korizky A.V., P.A.Hertzen Moscow Research Oncological Institute (MROI), RU

Some of the properties of the medicinal forms and tools, supposed to be used as hyperthermia modulators, can be evaluated by the atomic force microscopy (AFM): sizes and concentration of nanoparticles, their capability for the [...]

Hybrid Nanoparticles Targeted by Antitumor Antibodies and Emitting Alpha-particles

Resheto I.V., Deev S.M., Chuvilin D.Y., Panchenko V.Y., Sukharev S.S., Streltsova E.A., P.A.Hertzen Moscow Research Oncological Institute (MROI), RU

We describe a new therapeutic nanoparticle’s design, which consists of three parts: targeting, effecter and linker. Targeting part: an anti-HER2/neu mini-antibody-barnase fusion protein (4D5 scFv-barnase-His5). The anti-HER2/neu mini-antibody could be used to deliver barnase to [...]

Preliminary studies of new photosensitizer for photodynamic treatment of melanoma based on nanostructural forms of Bacteriochlorin p N-alkoxycycloimide alkoxyoxyme methyl ester

Meerovich G.A., Meerovich I.G., Meerovich G.A., Meerovich I.G., Grin M.A., Pozdeyev V.I., Tsiprovskij A.G., Oborotova N.A., Loschenov V.B., Yu.Baryshnikov A., Mironov A.F., A.M. Prokhorov General Physics Institute of RAS, RU

This work is devoted to investigation of Bacteriochlorin p N-alkoxycycloimide alkoxyoxyme methyl ester which possesses its absorption band at 795-800 nm. We have estimated the applicability of PDT with this photosensitizer to treat melanoma. We [...]

Atomic Force Microscopy as a Tool for Research in Oncocytology

Reshetov I.V., Chissov V.I., Volchenco N.N., Sukharev S.S., Slavnova E.N., Ivanov Yu.S., P.A.Hertzen Moscow Research Oncological Institute (MROI), RU

Most of investigations have studied specimens prepared by complex techniques which are unusual for hospitals. In present paper Scanning Probe Microscopy (SPM) has been used for searching signs of malignancy in specimens prepared identically to [...]

Contrasting agent for magnetic resonance imaging based on nanostructural dispersion of Manganese derivative of phthalocyanine: preliminary investigation results

Meerovich G.A., Meerovich I.G., Meerovich G.A., Meerovich I.G., Dolotova O.V., Uchevatkin A.A., Yu. Saveliev O., Yu.Baryshnikov A., Andronova N.V., Oborotova N.A., Kaliya O.L., Pirogov Yu.A., Vorozhtsov G.N., Yu.Baryshnikov A., N.N. Blokhin Russian Cancer Research Center or RAMS, RU

Contrast agents (CA) are used to increase tumor contrasting in magnetic resonance imaging (MRI). The work is devoted to estimation of Manganese chloride tetra-3-phenylthio-tetra-5-tert-buthylphthalocyanine [3-(PhS)4-5-(t-Bu)4PcMnCl] as potential CA for MRI. We have developed the micellar [...]

Optical chemical sensors on the base of arrays of ink-jet printed micro- and nanoparticles
