Respirocytes: Popular Nanorobot in Healthcare

Respirocytes are blood-borne spherical 1 m diameter nanorobots designed as artificial mechanical red blood cells. The outer shell is a diamondoid pressure vessel of 1000 atm with reversible molecule-selective pumps. Respirocytes are responsible for transporting oxygen and carbon dioxide molecules throughout the body.

The respirocyte is made up of 18 billion atoms carefully arranged in diamondoid pressure tanks capable of holding 3 billion oxygen and carbon dioxide molecules. The respirocyte would deliver 236 times more oxygen to body tissues than natural red blood cells.

The carbonic acidity could be managed by the respirocyte, which was controlled by gas concentration sensors and an onboard nano computer.

Molecular pumps control the release of stored gases from the tank. Respirocytes exchange gases via molecular rotors. For different types of molecules, the rotors have different tips. Each respirocyte contains three types of rotors. One rotor releases the stored oxygen as it travels through the body. The second type of rotor absorbs all carbon dioxide in the bloodstream and delivers it to the lungs, whereas the third rotor uses glucose from the bloodstream as an energy source. The equator is surrounded by twelve identical pumps, with oxygen rotors on the left, water rotors in the middle, and carbon dioxide rotors on the left. On the surface of the respirocyte, there are gas concentration sensors.

As the respirocyte passes through the lung capillaries, where O2 partial pressure is high and CO2 partial pressure is low, the onboard nano computer commands the sorting rotors to load in oxygen and release carbon dioxide molecules; as a result, the onboard nano computer commands the sorting rotors to load in oxygen and release carbon dioxide molecules—the water ballast chambers aid in maintaining buoyancy. The respirocytes can scavenge carbon monoxide and other poisonous gases from the body.

By imitating an erythrocyte’s oxygen and carbon dioxide transport functions, the respirocyte functions as an artificial erythrocyte. A 5 cc therapeutic dose of 50 percent respirocyte saline suspension containing 5 trillion nanorobots would completely replace the patient’s 5.4 liters of blood’s gas-carrying capacity. Once the therapeutic goal has been met, the respirocyte can be removed from circulation, necessitating a respirocyte activation protocol. The blood to be cleared would be passed from the patient to a specialized centrifugation apparatus where ultrasonic transmitters would command the respirocyte to maintain neutral buoyancy during the nanapheresis procedure. Because no other solid blood components can maintain neutral buoyancy during centrifugation, those components precipitate outwards. Blood components are reintroduced into filtered plasma. The filtered plasma is combined with centrifuged solid blood components before being returned undamaged to the patient’s body.
