DNA on the move

Everyone has heard of nanobots. little tiny machines that can go inside the body and do things that doctors cannot. yet, the idea of a machine the size of DNA seems almost science-fiction. new breakthroughs in nanobot technology aim to quell these acqusations. a New York chemistry lab has developed a form of nanobot that is almost the shape of a spider. unlike previous nanobots which have just been sticks or simple machines that can move left to right, these spiders can move and pick things up. these nanobots are still toddlers in comparison to what they can become in time.

Nanobots are the technology of the future. now they can only move about 50 steps, but in time armies of these things can enter the human body and target diseased tissue better then any chemical or medicine. the new spider nanobots are just bits of DNA that are put together in special ways. DNA on its own is a unreactive and stable substance. it is made of four basic chemical building blocks, A, T, G, and C, twisted in a double-helix. yet, scientists have found a way to make the secquence turn into propulsion. this is all do to the surface it walks on. in 2006 a biologist folded DNA strands into simple shapes like triangles and stars. so scientists use this technology by programming the DNA in the shape to move the nanobot. the "origami", as it is called, of DNA forms a trail for the nanobots to follow.

Nanobot technology can become the most useful asset in the world. if we can one day program these nanobots to enter a body and target cancer, then we can make them more accurate then any surgeon can ever be. these little machines of DNA can kill cancer wherever it is in the body. this may not only be the easiest way to fight cancer, but it probably is the safest.
