Nanomedicine and Drug Delivery
Nanomedicine is medical technology that is really, really small. Usually, researchers working in the field of ‘nanotechnology’ define it as being made of structures that have dimensions of between 1 and 100 nanometres. One type of nanotechnology is a ‘nanoparticle’, a tiny engineered capsule that can be used to deliver drugs. How big is a nanoparticle?
Well, each of our bodies are made up of around 10 trillion (10,000,000,000,000) cells. So cells are already tiny. But you can fit about 200 billion (200,000,000,000) nanoparticles inside one single cell. So nanoparticles are really tiny! The picture below from this paper shows the scale we are talking about:
We are researching different kinds of nanoparticles for delivering drugs to enhance bone and skin repair. We use different sorts of nanoparticles, including liposomes, polymersomes, nanodroplets and microbubbles, and clay particles.
