New DNA Robots Strut Their Tiny Stuff.

DNA robots are promising products of innovation mostly due to significant research and development investment. They move in response to chemical reactions and operate as nano-factories that may help deliver medicine to difficult-to-reach sites in the body, e.g.: tumours, etc. DNA robots are at the forefront of interdisciplinary research combining synthetic chemistry, enzymology, structural nanotechnology and computer science. Moreover, they illustrate what science can produce when funds are available. But do we need DNA robots? Are DNA robots the future of pharmaceutical innovation? How many more lives will we save with DNA robots? They may be the exact solution we need for many illnesses but they will not be available for many years to come. Given the slow assimilation rate of new technologies in emerging markets (mostly for practical reasons), it's unlikely DNA robots will ever feature on a formulary in the next 50 years and it may take 200 years for it be considered an "essential medicine".

For the first time, microscopic robots made from DNA molecules can walk, follow instructions and work together to assemble simple products on an atomic-scale assembly line, mimicking the machinery of living cells, two independent research teams announced Wednesday.

These experimental devices, described in the journal Nature, are advances in DNA nanotechnology, in which bioengineers are using the molecules of the genetic code as nuts, bolts, girders and other building materials, on a scale measured in billionths of a meter. The effort, which combines synthetic chemistry, enzymology, structural nanotechnology and computer science, takes advantage of the unique physical properties of DNA molecules to assemble shapes according to predictable chemical rules.
