What would be the physical appearance of a human who has been injected with medical nanorobots?
In most cases a human patient who is is undergoing a nanomedical treatment is going to look just like anyone else who is sick. The typical nanomedical treatment (e.g. to combat a bacterial or viral infection) will consist of an injection of perhaps a few cubic centimeters of micron-sized nanorobots suspended in fluid (probably a water/saline suspension). The typical therapeutic dose may include up to 1-10 trillion (1 trillion = 1012) individual nanorobots, although in some cases treatment may only require a few million or a few billion individual devices to be injected. Each nanorobot will be on the order of perhaps 0.5 micron up to perhaps 3 microns in diameter. (The exact size depends on the design, and on exactly what the nanorobots are intended to do.) The adult human body has a volume of perhaps 100,000 cm3 and a blood volume of ~5400 cm3, so adding a mere ~3 cm3 dose of nanorobots is not particularly invasive. The nanorobots are going to be doing exactly what the doctor tells the
