DEVICE FOR ELECTRIC STIMULATION OF CELLS

摘要

FIELD: electrical engineering.SUBSTANCE: device contains a culture plate with basins and a cover. Mounted on the plate cover is a prototype board having electric buses and electrodes. The electrodes are designed so that to enable immersion into the culture medium for contacting the base at the basin bottom. Two electrodes are placed in each basin. Each electrode is cylindrical-shaped, its radius being no less than 0.1 mm and no more than 5 mm to ensure the required rigidity and contract ohmic resistance to the basin base when a potential is supplied to the conductive base placed at the basin bottom. Arranged in the plate cover are holes with a diameter not in excess of one and a half electrode diameter, intended to accommodate electrodes so that to ensure their free stroke and protection against penetration of external factors in the process of the cell growth. Each cylindrical electrode is mounted on the prototype board by means of an arm at an angle of 90°. The base of each basin may be designed in the form of a conductive percolate grid with mesh pitch not in excess of the size of a cell to be cultivated.EFFECT: enhanced stimulating effect of electric field onto a single cell and uniform distribution of electric field lines within the basin bottom zone.5 dwg
