Background:

• Framework nucleic acids (FNAs) leverage Watson-Crick base pairing for programmable nanoscale assembly.
• Advancements in DNA nanotechnology have enabled the evolution of FNAs from 1D to 3D structures.
• Metal-framework nucleic acids (mFNA) represent a new class of nanomaterials integrating FNAs with inorganic components.

Purpose of the Study:

• To introduce the concept of metal-framework nucleic acids (mFNA) for the first time.
• To explore the fundamental connections between nanoscale FNAs and metal materials.
• To review the construction methods, functional characteristics, challenges, and future prospects of mFNA.

Main Methods:

• Utilizing framework nucleic acids (FNAs) as precise templates for guided assembly of metal ions and nanoparticles.
• Incorporating metal salts, metal nanoclusters, metal nanoparticles, or metal oxide nanoparticles into FNA structures.
• Reviewing existing literature on FNA principles and metal nanomaterial properties to define mFNA.

Main Results:

• mFNA are synthesized by templating metal ions/nanomaterials using FNAs, creating hybrid organic-inorganic nanostructures.
• mFNA inherit programmable self-assembly from nucleic acids and unique physicochemical properties from inorganic components.
• These hybrid nanomaterials exhibit broad application potential across biology, chemistry, materials science, and energy science.

Conclusions:

• mFNA represent a significant advancement in nanomaterial design, bridging organic and inorganic chemistry.
• Further research into mFNA construction and functionality is crucial for unlocking their full application potential.
• Addressing current challenges in mFNA development will pave the way for future innovations in nanotechnology.
