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.
