DNA origami: The bridge from bottom to top
Conventional top-down nanofabrication, over the last six decades, has enabled almost all
the complex electronic, optical and micro-fluidic devices that form the foundation of our
society. Parallel efforts, exploring bottom-up self-assembly processes, have also enabled
design and synthesis of structures like quantum dots, carbon nanotubes and unique
bio-molecules that possess technologically relevant proper- ties unachievable top-down.
While both these approaches have independently matured, ongoing efforts to create “hybrid
nanostructures” combining both strategies, has been fraught with technical challenges. The
main roadblock is the absence of a scalable method to deterministically organize
components built bottom-up within top-down nanofabricated structures.
In this talk, I will first introduce a directed self-assembly technique that utilizes DNA
origami1 as a molecular adaptor to modularly position, and orient, bottom-up
nano-components (like quantum dots, light emitters and proteins) within top-down
nanofabricated devices.2 I will then present experimental results demonstrating the
utility of the technique to achieved absolute, arbitrarily scalable, control over the
integration of discrete emitters inside optical devices.3,4 Finally, I conclude by
presenting my vision of how DNA origami assisted modular bridge between top-down and
bottom-up nanofabrication can enable a range of highly transformative, functional,
devices. Specifically, I will discuss unpublished data demonstrating arrays of
single-photon sources, platform for studying bio-chemical networks with discrete
components and designs for using this technology for real-time highly-multiplexed protein
quantification.
