Some typical examples of medical nanorobots

Entry	Nanorobot types	Key characteristics	Refs.
1	Pharmacyte	A medical nanorobot with a diameter of 1–2 μm Molecular indicators or chemotactic sensors are used to ensure the precision of the targeting system They can be eliminated or recuperated through centrifuge nanapheresis after finishing the tasks	[52]
2	Microchips	Nanorobots possess microchips which can conduct current signals once the molecules detect a disease The benefits are the small charge to yield and simple to operate	[53]
3	Respirocyte	A type of nanorobot that carries oxygen like an artificial red blood cell The power is achieved through endogenous serum glucose	[54]
4	Microbivores	The nanorobot is flat and spheroidal in shape for nanomedical uses With a diameter of 3.4 μm along its main axis and a diameter of 2.0 μm on the minor axis It has the phagocytic capability which is almost 80-fold higher proficient than other macrophages	[55]
5	Clottocytes	They have the ‘instant’ hemostasis biological activity which is called artificial mechanical platelets They also transport substances that assist in the coagulation process	[56]
6	Chromallocyte	The renovation machine will first assess the condition by inspecting the cellular substances, actions, and works These repair machines are capable of overhauling the complete cell	[57]
