Under the weather? Just swallow a doctor
Abstract:
The day when patients can "swallow their doctor" has come a step closer with the development of a submicroscopic nanoparticle that acts as an intelligent pill to deliver drugs when and where they are needed in the body.
Each nanoparticle is built to target a specific part of the body and to release their drugs in a controlled manner over a given period of time. They are so small that millions of them could be injected into the bloodstream without harming healthy tissues.
Scientists at the Massachusetts Institute of Technology (MIT) in Cambridge have designed the first nanoparticles designed to target the walls of the arteries around the heart. They bind specifically to the proteins that only stick out from the inner lining of the these blood vessels when they are damaged.
