Nanorobots & DNA Origami — Dr Shelley Wickham

Most drugs work by flooding the body with a particular molecule, in the hope that they will do their work where they’re most needed, and not damage the rest of the body along the way. What if you could design a programmable, nano-sized robot that could detect where it is and whether it’s safe to release its drug cargo, to target disease in just in the right place at the right time?

At the University of Sydney, Shelley uses self-assembling nanorobots made from DNA to solve all sorts of biomedical problems, from cancer detection and drug delivery, to monitoring health and reading early signs of heart disease.

  1. All fine, but I've seen very similar pictures in 2000. 20 years later – no working devices are used in medicine.
    Nanotech is no more on the front page. Starts to look like nuclear fusion – ideas were all exposed in the 1960s – but no reactor built yet. And will not be built until 2050-2100.
