Research

I am interested in an interdisciplinary field between systems engineering (especially robotics) and nano-bio engineering. Varieties of systems, from nanoscale to macroscale, have been developed with my colleagues and collaborators, using DNA nanoengineering as a core technology and by combining with a wide range of nano- and micro-scale technologies:

  • Contents will be updated after the publication of Sci. Robotics paper

Machines & Robots

  • Meso-microscale: DNA-based machines powered by artificial metabolism [NEW]
    • Novel "quasi-locomotive" device for molecular robots
    • (to be updated)

Material systems

  • Meso-microscale: Dynamic self-regenerating DNA material by artificial metabolism [NEW]
    • Point-of-care (POC) pathogen detection platform
    • (to be updated)
  • Macro (Bulk) scale: DNA hydrogels
    • Biofunctionalized material for architectural building blocks (Collaboration with Sabin Lab (Cornell))
    • Stimuli-responsive materials
Macroscale: DNA Hydrogel - Ceramic hybrid component (PolyBrick 3.0)

Nanostructures

  • T-motif: an "artificial" DNA junction for nanostructures
    • 1-D and 2-D Nanostructures (Ladder, Planar, Rings)
    • Chemical self-replication system (self-replicating DNA rings) (Collaboration with Park Lab (SKKU))
  • Substrate-assisted self-assembly: scaling-up technology for DNA self-assembly
    • Fabrication of micron-scale 2-D crystals
  • DNA-origami-based polymorphic nanostructures
