**Programmable DNA self-assembled nanostructures**
Ibon Santiago
Self-assembly, CIC nanoGUNE
DNA is a remarkable material for building supramolecular structures of almost
arbitrary geometry from the ‘bottom up’, offering improved precision in
the rational design of nanostructures.
In this talk, I will show the formation of 2D and 3D nanostructures with near-
atomic precision using the self-assembly of DNA molecules whose interactions
are programmed through the design of their base sequences. Further, the
addressability of DNA nanostructures allows for functionalisation with
nanoparticles, proteins and hydrophobic moieties. Such hybrid self-assembled
nanostructures open the door to realising soft nanorobotic systems.
Measuring the dynamics of DNA nanostructures in solution is challenging.
Observation methods like TEM and AFM require surface immobilisation of the
nanostructures and are thus rather static. Here I will discuss our recent work
on DNA origami detection in solution through nanoimpact collisions on
ultramicroelectrodes and on lipid bilayers.
Also, actuation is needed to drive and control DNA nanodevices to perform
specific tasks. I shall describe our approach towards controlling and
measuring the linear and rotational motion of DNA origami nanostructures
driven by external fields.
