Currently, an urgent need in the field of wearable electronics is the development of flexible sensors that can be attached to the human body to monitor various physiological indicators and movements. In this work, we propose a method for forming an electrically conductive network of multi-walled carbon nanotubes (MWCNT) in a matrix of silicone elastomer to make stretchable sensors sensitive to mechanical strain. The electrical conductivity and sensitivity characteristics of the sensor were improved by using laser exposure, through the effect of forming strong carbon nanotube (CNT) networks.

- Development of stable, antithrombogenic coatings for cardiovascular implants is vital, particularly for devices like ventricular assist devices that experience high shear stress from blood flow.
- A new method involves creating layer-by-layer nanocomposite coatings using multi-walled carbon nanotubes (MWCNT) in a collagen matrix, with experiments showing enhanced resistance to shear stress with glutaraldehyde as a cross-linking agent.
- Testing via a reversible microfluidic device indicates that these collagen/c-MWCNT coatings exhibit lower protein adhesion compared to traditional titanium surfaces, suggesting their potential as durable and safe materials for cardiovascular applications.
The effect of single substitutions of protium for deuterium in hydrogen bonds between pairs of nitrogenous bases on the open states occurrence probability at high critical breaking energies of these bonds has been studied. The study was carried out using numerical methods based on the angular mathematical model of DNA. The IFNA17 gene was divided into three approximately equal parts.

However, the experimental study of DNA dynamics and the occurrence of open states is limited by the spatial resolution of available biophysical instruments.

When a DNA molecule passes from the region of high viscosity values to the region of low values, open states, denaturation bubbles, and unweaving of DNA strands can occur. Stabilization of the molecule is provided by energy dissipation-dissipation due to interaction with the environment.
