Abstract
The design of nanotechnologies capable of transporting drugs into the body and releasing them specifically at the site of action has made it possible to increase the therapeutic activity and reduce the toxicity of many drugs. These "nanovectors" are capable of protecting the active molecule from degradation by the body's enzymes, selectively delivering it to the target tissue or cell, and controlling its release. More specific than traditional pharmaceutical formulations, "nanomedicines" make it possible to design new therapeutic strategies in the fight against severe diseases: cancers, intracellular infections, metabolic or neurodegenerative diseases, etc.
