Processing DNA Storage through Programmable Assembly in a Droplet-Based Fluidics System.

Area of Science:

• Biotechnology
• Data Storage
• Synthetic Biology

Background:

• Digital data storage in synthetic DNA offers high density but lacks active processing capabilities.
• Current methods for DNA data storage are limited in their ability to actively edit or process information within DNA pools.

Purpose of the Study:

• To develop an active DNA data editing process for synthetic DNA pools.
• To enable random access and high-fidelity processing of digital information encoded in DNA.
• To demonstrate the synthesis of DNA pools containing image and animation data.

Main Methods:

• Utilized splint ligation within a droplet-controlled fluidics (DCF) system for DNA data editing.
• Synthesized DNA fragments of discrete sizes (100-500 base pairs) for droplet assembly and programmed sequence exchange.
• Employed polymerase chain reaction amplification for random access and address primer scanning for high-fidelity decoding.

Main Results:

• Successfully demonstrated an active DNA data editing process in a DCF system.
• Achieved programmed sequence information exchange and synthesis of determined DNA pools with random access.
• Synthesized DNA pools encoding pixel information (PNG) and an animation movie file (MP4) with high fidelity.

Conclusions:

• The developed splint ligation method in DCF systems enables active processing of DNA data.
• This approach allows for random access and high-fidelity retrieval of digital information stored in synthetic DNA.
• The successful encoding and synthesis of image and animation data highlight the potential for DNA-based media storage.
