• To demonstrate the versatility of NuABD-based platforms with different nucleic acid scaffolds.

Main Methods:

• Utilized NuABDs in conjunction with nucleic acid scaffolds (e.g., G-quadruplex DNA, DNA nanoflowers).
• Investigated thermodynamic and electrochemical properties of the dyes.
• Performed controlled atom-transfer radical polymerization (ATRP).

Main Results:

• Demonstrated NuABDs as effective photocatalysts for precisely controlled ATRP when paired with nucleic acid scaffolds.
• Gained insights into the mechanism driving photopolymerization through property investigations.
