Team Nanoscooter Braunschweig
| Project idea: Building the world´s smallest car
DNA is not only a polymer which stores genetic information. Because of its complementary nucleobases DNA provides the opportunity to build complex structures – so called DNA origami – and use them as a template to investigate interactions of molecules, proteins and nanoparticles or as vehicle to transport cargo. Our team designs a nanoscale car consisting of DNA which we called Nanoscooter (from 'Autoscooter', german for 'bumper car'). This Nanoscooter becomes motile on mica surfaces by adapting the kind and concentration of cations in the buffer. Directed movement is achieved by the of repulsion of oxygen gas which is produced at platinum nanoparticles tethered to the back of the Nanoscooter. The shape of the DNA origami is confirmed by atomic force microscopy, while the movement of the car on a flat mica surface is illustrated by fluorescence microscopy using fluorescent beads. This type of DNA origami can be used for directed transport of different components. In the future this technology could be used for the supply in nanoscale factories or as a lithographic pen by controlling the location of nanoscale catalysis.
