The properties of the biological tissue laser nanowelding have been investigated. The high thermo- and photo stability of the solder composition based on the water albumin dispersion with the single-layer and multi-layer carbon nanotubes has been demonstrated. The specimens of the bull trachea cartilage and the pig skin were investigated as the biological tissue objects in vitro. The nanosolder usage allowed a several times increase of the tensile strength of the laser welds of a relatively traditional solder based on the albumin dispersion. The results have demonstrated the potential possibilities of a laser solder for welding of the biological tissues.

The superconducting film magnetic field concentrator has been investigated. It has been determined that nanostructuring of an active strip of the magnetic field concentrator on the superconducting branches and cuts (width of cuts is 20 nm) allows a several times increase of the concentration coefficient of the magnetic field, and, therefore, a reduction of the threshold sensitivity of the magnetic film sensor or its geometric dimensions. Thus, the higher values of the concentration coefficient are achieved in the magnetic field concentrator based on films from a low-temperature superconductor material compared to the concentrator based on films from a high-temperature superconductor material.
