Optical Clearing as Method to Increase the Depth of Nanoparticles Detection in the Skin with OCT-Visualization

Background and Objectives: Nanoparticles of titanium dioxide are now widely used both for the creation of sunscreen filters, and as carriers of drugs. One of the ways of transepidermal delivery of these nanoparticles to the dermis of the skin is their penetration into the hair follicles. However, optical control of the filling of follicles with nanoparticles is rather difficult due to strong light scattering in the skin.

Influence of the Hydrogen Bond on the IR-spectrum and Structure of Molecular Complex of Diamond Nanoparticles and DNA Bases

Background and Objectives: Using molecular modeling by the density functional theory method we analyze a hydrogen bonds formation and their influence on IR-spectrum and structure of molecular complex which is formed as the interaction of complementary couple of DNA nucleobases adenine and timin and nanodiamonds surrounded with carboxylic groups. As an example of nanodiamonds adamantine has been used. Intermolecular forces and structure of hydrogen bonds are investigated.


В данной работе рассматривается высокочувствительная аналитическая методика – гигантское комбинационное рассеяние света. С помощью этой методики становится возможным обнаружение одной молекулы вещества в растворе. Стоит отметить, что гигантское комбинационное рассеяние является неинвазивной техникой исследования и для исследования биобъектов может быть скомбинировано с другими методиками, такими как микрофлюидика или лазерный пинцет.

The influence of Morphology, Conditions of Production and External Effects on Nanoparticles’ (in Terms of Iron) Dielectric Properties

It was shown that the complex research of iron nanoparticles properties by different methods, supplemented each other, permit to receive the data about the interior sizes of nanoparticles, a number of physical properties of particles, their dependence on frequency and changes produced by various influences. It was found that the conductivity of nanoparticles changed under the square dependence σ = σo*ω2.
