Engineering a custom-sized DNA scaffold for more efficient DNA origami-based nucleic acid data storage.

Area of Science:

• Biotechnology
• Nanotechnology
• Data Storage

Background:

• DNA data storage offers a promising solution for increasing data demands.
• Current structure-based DNA data storage uses DNA origami and DNA-PAINT for reading/writing data.
• Larger DNA origami structures can improve data storage efficiency but require longer DNA scaffolds.

Purpose of the Study:

• To engineer a novel, longer DNA scaffold for creating larger rectangle origami structures.
• To expand the capabilities of the origami-based digital nucleic acid memory (dNAM) approach.
• To enhance the efficiency and scalability of DNA data storage.

Main Methods:

• Engineering of a novel, longer single-stranded DNA scaffold.
• Self-assembly of the scaffold into a larger rectangle origami platform.
• Confirmation of correct assembly and DNA data strand positioning using atomic force microscopy and DNA-PAINT super-resolution microscopy.

Main Results:

• Successful engineering of a novel longer DNA scaffold.
• Demonstrated self-assembly into the desired larger rectangle origami structure.
• Verified correct positioning of DNA data strands on the origami platform.
• Achieved a 67% increase in data points per origami structure.

Conclusions:

• The novel DNA scaffold enables the production of larger DNA origami.
• This advancement supports the expansion and scalability of origami-based dNAM.
• The improved structure enhances data density for DNA data storage applications.
