Scientists in Sweden today reported a nanoengineering innovation that offers hope for treatment of cancer, infections and other health problems – conductive wires of DNA enhanced with gold which could be used to electrically measure hundreds of biological processes simultaneously.
While DNA nanowires have been in development for some time, the method developed at KTH Royal Institute of Technology and Stockholm University produces a unique three-dimensional biosensor for better effectiveness than flat, two-dimensional sensors. “Our geometry makes it much easier to measure several biomolecules simultaneously, and is also 100 times more sensitive,” says KTH Professor Wouter van der Wijngaart.
