Review of: "In general, an electrical nano-biosensor consists of an immobilized static biological system ( based on their own built-in immobilized static biological system)"

The development of biosensors to measure the concentration of dissolved oxygen in the blood began. This sensor is also called COBD because it covers the surface of the electrode with an enzyme whose constituent is sometimes called (electro-calorie). Later, it helped oxidize glucose. This sensor was used to measure blood sugar. In the same Bapvshandn electrode, an enzyme that has the ability to convert urea into ammonium carbonate in the electrode material ++ ion, NH4, was used to create biosensors that could measure the urea in the blood or urine. Each of these two early biosensors used a different transducer in its signal conversion section . In the first type, blood sugar was measured by measuring the…
