Main Methods:
- Introduced a 'grafting to' method for DNA-polymer conjugation with high efficiency (70-90%) under ambient conditions.
- Generated homo and block copolymers from acrylate, methacrylate, and acrylamide families.
- Coupled synthesized polymers to single-stranded DNA (ssDNA) and hybridized them to DNA-origami scaffolds.
Main Results:
- Achieved high conversion rates in DNA-polymer conjugation.
- Successfully patterned various DNA-origami architectures with precise surface nanopatterns.
