Digital data storage on DNA tape using CRISPR base editors.

Area of Science:

• Biotechnology
• Molecular Engineering
• Data Storage

Background:

• Archival digital memory faces physical limitations with increasing data demands.
• DNA offers superior durability, capacity, and energy efficiency for data storage.
• Existing DNA data storage methods often rely on non-scalable, waste-producing synthesis techniques.

Purpose of the Study:

• To develop an industrially scalable and environmentally friendly DNA-based digital data storage system.
• To leverage CRISPR base editing for efficient and targeted information writing on DNA.
• To demonstrate a proof of concept for the DNA Mutational Overwriting Storage (DMOS) system.

Main Methods:

• Utilized combinatorial, addressable, orthogonal, and independent in vitro CRISPR base-editing reactions.
• Developed a system inspired by semiconductor memory architecture and gene editing advancements.
• Wrote data onto a pool of greenly synthesized DNA tapes.

Main Results:

• Successfully demonstrated writing and accurate reading of digital data on DNA tapes.
• Stored a bitmap image of a school logo and the study's title as proof of concept.
• Validated the feasibility of the DMOS system for molecular digital data storage.

Conclusions:

• The DMOS system presents a viable, eco-friendly alternative for digital data storage.
• CRISPR base editing enables efficient and addressable data writing on DNA.
• This technology addresses the limitations of current digital memory and unsustainable DNA synthesis methods.
