Carbonaceous microsensors DEVICE FOR DETERMINING dopamine concentration for long-term implantation in the mammalian brain

摘要

The invention relates to the field of experimental medicine, in particular to the creation of implantable electrodes for in vivo study of central nervous system of mammals by voltammetry. Technical result is directed to the utility model is to improve processability microsensor due to use as a basis for the growth of carbon nanotubes commercially produced microwire in glass insulation. The technical result is achieved in the microsensor, wherein at the end of the segment industrially manufactured microwire to a metal conductor (e.g., nickel) in the insulating sheath (e.g., glass), previously coated (e.g. by magnetron sputtering) with one end of the catalyst for carbon nanotube growth ( for example, a thin layer of iron, nickel or cobalt) in electrical contact with a living microwire, in which carbon nanotubes are synthesized (e.g., by catalytic PYROL of hydrocarbons, in particular of acetylene). NP 1, PO 4, 1 IL.
