The new world of health started since nanotechnology has demonstrated that it will be possible, in a next future, to identify diseases at the earliest stages — at the cellular level — and to deliver therapeutic drugs (that are only activated when they reach their target) directly to the disease site reducing their toxicity. This revolutionary change in the dimensions of our “medical approach” is going to take us closer to our inner natural dimensions and to make us to appreciate all those things that belong to the nano-sized world.
