Nanotechnology's "magic bullet"
The ideal drug carrier may be something out of science fiction. In principle, it is injected into the body and transports itself to the correct target, such as a tumor, and delivers the required dose at this target. This idealized concept was first proposed by Paul Ehrlich at the beginning of the 20th century and was nicknamed the "magic bullet" concept. With the advent of nanotechnology and nanomedicine this dream is rapidly becoming a reality. Nanotechnology has already been applied to drug delivery and cosmetics through the use of liposomal technology, and now nanoparticles and nanotubes present an exciting and more promising alternative.
