To date, the most effective method of fixing is injection silicate. This technique can significantly reduce the subsidence of the base and prevent various deformations of the building. Injection silicatization is widely used both in the Russian Federation and in foreign practice due to the technical efficiency, high degree of reliability and minimum amount of excavation.

We present a brief description of the optogenetic investigation stages. Various types of implantable devices generating and recording signals in excitable tissues have been considered. The features of control signal transduction inside living tissues were analyzed. We discussed the possibility of medical and biological use of optical fibers for excitable tissues stimulation. Then we proposed a device of an implantable optical-electrode system for scanning and controlling the bioelectric parameters. The device can be used in medical diagnostics, prosthetics, myostimulation, neurostimulation and cardioacceleration, for instance, at neurological and rehabilitation medical institutions. With this in mind, an attempt will be made to make special combined microelectrode arrays to implant them into living tissue. The arrays should be able to change their profile according to the implantation-area contour and biophysical features of the substrate surface. It is necessary to provide a point generation and layer-by-layer scanning of excitation pulse through integration of individual microelectrode arrays into a single test-system.

The problems of delivery, embedding and monitoring the expression of opsin genes into the cell genome of interest have been considered. In the article, the parameters and properties of various opsins and also the main ways of achievement of precise optical control over cell using opsins were presented. The rules for choosing the parameters of a light beam and the features of its putting were pointed out. The characteristic properties of the different measurement technique and recording the experimental quantities were analyzed and given.
