Currently, tissue engineering technologies are promising for the restoration of damaged organs and tissues. For regeneration of electrically conductive tissues or neural interfaces, it is necessary to provide electrical conductivity for the transmission of electrophysiological signals. The developed biocomposite structures presented in this article possess such properties.

- 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.
A technology for the formation and bonding with a substrate of hybrid carbon nanostructures from single-walled carbon nanotubes (SWCNT) and reduced graphene oxide (rGO) by laser radiation is proposed. Molecular dynamics modeling by the real-time time-dependent density functional tight-binding (TD-DFTB) method made it possible to reveal the mechanism of field emission centers formation in carbon nanostructures layers. Laser radiation stimulates the formation of graphene-nanotube covalent contacts and also induces a dipole moment of hybrid nanostructures, which ensures their orientation along the force lines of the radiation field.
