DNA materials: bridging nanotechnology and biotechnology

Area of Science:

• Biotechnology
• Nanotechnology
• Materials Science

Background:

• DNA serves as both the genetic molecule and a versatile material for nanoscale engineering.
• DNA's unique properties include biological function, biocompatibility, molecular recognition, and nanoscale controllability.
• Novel DNA materials bridge nanotechnology and biotechnology for diverse applications.

Purpose of the Study:

• To describe the design and construction of DNA materials.
• To categorize DNA materials as substrates or linkers.
• To highlight applications of DNA materials in various fields.

Main Methods:

• DNA materials designed as substrates utilize enzymatic reactions (e.g., ligation, polymerization).
• DNA materials designed as linkers interface with nanoparticles, proteins, and lipids.
• Enzymatic ligation used to create DNA hydrogels and protein-producing DNA hydrogels.
• Thermostable branched DNA developed as modular primers for polymerase chain reaction (PCR).

Main Results:

• First bulk hydrogel made entirely of DNA created using enzymatic ligation.
• Protein-producing DNA hydrogel scaffold developed.
• Thermostable branched DNA demonstrated utility as PCR primers.
• Physical DNA hydrogel with unique structure and mechanical properties constructed via enzymatic polymerization.
• DNA-protein conjugate designed as a universal adapter for protein detection.

Conclusions:

• DNA materials show significant potential as substrates and linkers.
• Applications span diagnostics, protein production, drug delivery, life evolution studies, and plasmonics.
• Further development is needed to address challenges in design, fabrication, scaling, and cost for widespread adoption.
