Creating DNA Nanonetworks for Early Disease Detection and Drug Delivery

Nanotechnology offers exciting possibilities for the future of healthcare. Because of the tiny size of nano-devices, they are difficult to design and produce. Self-assembly, which involves taking simple structures and allowing them to combine to form larger, more complex structures, could be a solution to this problem. There are many examples of self-assembly in nature, such as the formation of DNA. Dr Florian Lau and his colleagues at the Institute of Telematics in Lübeck, Germany, research how to alter special building blocks of DNA – which they call ‘tiles’ – in such a way that allows them to self-assemble into ‘nanonetworks’.
