|Title:||DNA nanostructures as building blocks for molecular biophysics and future therapeutics|
|Date:||Thursday Jun 6, 2013|
Our group previously solved a key challenge for nanotechnology: programmable self-assembly of complex, three-dimensional nanostructures. Our solution was to build custom three-dimensional structures that can be conceived as stacks of nearly flat layers of DNA. I will discuss applications of this technology for molecular biophysics and therapeutics: (1) weak-alignment media for NMR structure determination of membrane proteins such as UCP2, a 30 kDa six-transmembrane helix mitochondrial proton transporter; (2) scaffolds for determining the number of SNARE complexes required for lipid-bilayer fusion; (3) how shape and size of DNA nanoparticles affects the rate of cellular internalization.
