DNA Origami Nanoarchitectures for Spatially-Oriented Macromolecular Organization
Scaffolded DNA origami nanoparticles (DNA-NPs) have enabled synthesis of biomimetic
nanoarchitectures that mimic natural protein assemblies such as toxins and viruses with high
structural fidelity. Unlike other types of synthetic self-assembled materials, these DNA-NPs can
be designed to any prescribed shape and size. In addition, these DNA-NPs can be easily modified
to precisely organize biomolecules with an unprecedented control over their stoichiometry and
spatial organization. These nanoparticles have enabled the development of biomimetic system
such as viral like nanoparticles mimics, bio-inspired light harvesting system, and enzymatic
cascade reconstitution among others. In this talk, I will introduce our approach to design and
assemble 3D DNA nanostructures that can be utilized as a platform to precisely organize organic
and inorganic molecule assemblies at the nanometer scale. Next, I will presents results validating
the controlled 3D arrangement of proteins, which enabled an investigation of the role of viral
proteins nanoscale organization on immune cell receptor toward efficient vaccine platform
development. Then I will demonstrate the capacity of scaffolded DNA building blocks to organize
strongly interacting cyanine aggregates in order to construct fast, coherent energy transfer in
complex supramolecular architectures. This approach may enable design of nanoscale excitonic
circuit in large 2D and 3D DNA-based arrays.
Biography:
Remi Veneziano joined the department of Bioengineering at George Mason University in the Fall
of 2018 with the objective of developing a highly translational-research program focusing on using
DNA nanotechnology for biomedical applications including targeted delivery of biologics (RNA,
proteins), vaccine platform development, biophysical characterization of DNA nanoparticles
interaction with lipid bilayer membranes, and synthesis of new composite biomaterials. Prior to
this position, he was a Postdoctoral Associate at MIT under the supervision of Pr. Mark Bathe,
where he worked on various aspect of DNA nanotechnology including the development of a new
type of 3D wireframe DNA nanoparticles. He also designed DNA-nanoparticles for HIV antigens
presentation with the aim of understanding the relation between nanoscale organization of antigens
and immune response.
