Nucleic Acid Memory - Boise State University
Position: Research Scientist (2019-2022)
Location: Material Science & Engineering Department, Boise State University
PI: Dr. Will Hughes
Project Overview
Development of a DNA-origami based digital storage platform for encoding, storing, and reading digital information using chemically synthesized DNA and super-resolution microscopy.
Concept
DNA offers information density and stability advantages over traditional storage media:
- Information density: DNA can store data at densities far exceeding hard drives
- Stability: DNA remains stable for thousands of years under proper conditions
- Energy efficiency: No power required for storage
- Quaternary code: Uses A, G, C, T bases (4-state vs binary 2-state)
Technical Approach
DNA Origami Scaffold
- Used bacteriophage DNA as scaffold
- Programmed DNA to fold into "breadboard" structures
- Positioned staple strands at specific locations to encode information
Data Encoding
- Digital information encoded into DNA sequences
- Staple strands positioned to represent binary data
- Error-correction algorithms implemented
DNA-PAINT Readout
- Super-resolution microscopy technique
- Optically read encoded information at nanoscale resolution
- Achieved successful data recovery from DNA
Key Achievement
Successfully encoded and optically read the message: "Data is in our DNA!"
This demonstrated proof-of-concept for DNA-based information storage with optical readout.
