Kislov V., Gulyaev Yu., Medvedev B., Taranov I., Kolesov V., Kashin V., Gubin S., Khomutov G., Soldatov E., Artemiev M., Gurevich S., Russian Academy of Sciences, RU

This work is a result of a coherent effort of a consortium of Russian research groups in Nanotechnology (INTC - Interdisciplinary Nanotechnology Consortium) aimed at creating molecular electronic devices based on individual and collective properties [...]

DNA-Based Nanotechnology: Highly Luminescent CdSe – DNA Nanoscale – Engineered Complexes

Kislov V., Artemyev M., Khomutov G., Russian Academy of Sciences, RU

We present some new results within the concept of using DNA molecules as building blocks and nanotemplates for controllable fabrication of various bioinorganic nanostructures due to their unique physical-chemical properties and recognition capabilities and the [...]

SPM Investigation of the Electron Properties YSZ Nanostructured Films

Antonov D.A., Gorshkov O.N., Kasatkin A.P., Maximov G.A., Saveliev D.A., Filatov D.O., University of Nizhny Novgorod, RU

In present work, the electron properties of YSZ nanostructured films using combined Atomic Force Microscopy / Òunnel Spectroscopy (AFMTS) have been investigated.It was demonstrated, the implantation of the films ZrO2(Y) by zirconium ions reduced forming [...]

Experimental Observation of Carbon and Carbon-Metal Nanotoroids and New Carbon-Metal Superstructures at Nanoscale

Kislov V., Medvedev B., Taranov I., Russian Academy of Sciences, RU

We report experimental observation (by AFM, STM and HRTEM methods) of nanotoroids for both carbon and carbon-metal superstructures produced by methods of arc discharge and laser ablation. Size of superstructures is ~ 10 nm for [...]

Apoptosis of the Human Neutrophils under a Lipopolisaccharide (LPS) of Proteus Mirabilis Condition Observed in Real Time by Atomic Force Microscopy (AFM)

Pleskova S.N., Guschina Yu., Zvonkova M.B., Medical State Academy Nizhniy Novgorod, RU

The goal of present work was to receive the images of apoptosis process in dynamics after addition of Proteus mirabilis 210 LPS and to measure the mechanical properties change of neutrophils’ membranes. We observed the [...]

Nanotechnology Based on Spatially Fixed ds DNA (RNA) Molecules

Zakharov M.A., Yevdokimov Yu.M., Skuridin S.G., Nechipurenko Yu.D., Engelhardt Institute of Molecular Biology of RAS, RU

A new strategy of creating nucleic acid nanostructures is described. Our approach is based not on isotropic dsDNA (or RNA) molecules, but on these molecules fixed in spatial structure of their liquid-crystalline particles.The nanostructure formed [...]

The Evolution of Vievs of in vivo Use of Nanoparticles for Tumor Treatment

Chissov V.I., Reshetov I.V., Luskinovich P.N., Shepelev A.A, Efremov G.D., Matorin O.V., Sukharev S.S., P.A.Hertsen Moscow Research Oncological Institute (MROI), RU

The methods of site-specific delivery of antitumor agents without the general and system consecuences remain to be actual because the need to reduce the negative effects of antitumor treatment. In the experiment attempts are made [...]

Reconstruction of Load-Bearing Defects in Oncology by Using Nanomodification of Implants

Chissov V.I., Reshetov I.V., Levashov E.A., Shtansky D.V., Filushin M.M., Sukharev S.S., Bashkova I.A., Moscow Research Oncological Institute, RU
