Potapov V.V., Sobolev K.G., Gorev D.S., Russian Acadamey of Sciences; University of Wisconsin-Milwaukee, RU

Technology of production of new type of amorphous nano-SiO2 in the forms of sols, gels, and powders with precursor based on hydrothermal solution was developed. Amorphous nanodispersed silicon dioxide SiO2 is currently one of the [...]

Multiplex Express In Vitro Diagnostics based on Magnetic Nanoparticles

Nikitin M.P., Nikitin P.I., Guteneva N.V., Bragina V.A., Znoyko S.L., Orlov A.V., Gorshkov B.G., Nikitin M.P., Nikitin P.I., General Physics Institute, Russian Academy of Sciences, RU

Magnetic nanoparticles (MP) have provided many breakthrough solutions for life science. The immense potential of MP as labels in advanced immunoassays stems from the fact that they, unlike optical labels, can be easily detected inside [...]

Modeling the hydrogen and oxygen atoms interaction with the defects on a diamond surface

Lvova N.А., Ponomarev O.V., Ryazanova A.I., Moscow Institute of Physics and Technology (State University), RU

Diamond is a material comprising a number of unique properties. Some properties of diamond are of particular interest, namely: high thermal conductivity, high refractive index, transparency in a wide range of wavelengths, chemical inertness, and [...]

Stable Magnetic Isotopes as New Trend in Nanonuclear Biotechnology

Koltover V., Institute of Problems of Chemical Physics, Russian Academy of Sciences, RU

With dimensions of the order of tens angstroms, biomolecular devices are assigned, in modern terminology, to objects of “nanophysics”. At the same time, all of them are composed from chemical elements many of which have [...]
