During photothermal therapy an external light is used to illuminate tumor, the light is then absorbed by gold nanoparticles generating excessive heat that kills the cancer cells
.
Can nanotechnology make us immortal?
In 30 or 40 years, we’ll have microscopic machines traveling through our bodies, repairing damaged cells and organs, effectively wiping out diseases. The nanotechnology will also be used to back up our memories and personalities.
Can nanotechnology be injected?
Nanoparticles can be used for drug delivery purposes, either as the drug itself or as the drug carrier.
The product can be administered orally, applied onto the skin, or injected
.
How do nanobots enter the body?
