Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current archival digital data storage systems face challenges in achieving high density, low cost, and long-lasting storage solutions, as they are either slow or costly for data writing and recovery, and existing technologies do not effectively leverage the high information density and stability of DNA for digital data storage.
Innovation Solution
A processive enzyme molecular electronic sensor system that reads digital information encoded in DNA molecules directly, utilizing a chip-based format with a trans-impedance amplifier and processive enzymes like polymerase, reverse transcriptase, helicase, or exonuclease to extract data quickly and efficiently, allowing for high-throughput, low-cost, and fast data extraction without the need for sample preparation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional archival storage systems (magnetic tape, optical disc) are used, then data storage capacity and duration are achieved, but data writing and recovery processes are slow and costly
Solution Approach 1:
The patent replaces mechanical data reading systems (optical discs, magnetic tape) with a molecular-scale enzymatic system. Processive enzymes move along DNA molecules and read encoded information through biochemical reactions, eliminating the mechanical movement limitations of conventional storage retrieval systems and achieving much faster data access speeds.
Solution Approach 2:
The invention changes the fundamental operating parameters from macroscopic mechanical systems to molecular-scale biochemical systems. By using enzymes that process DNA at the molecular level, the system achieves data reading speeds limited only by enzyme kinetics rather than mechanical rotation or transport, dramatically improving productivity while reducing access time.
2Quantity of substance
If DNA is used for data storage, then extremely high information density is achieved, but complicated sample preparation (making copies, clonal populations) is required
Solution Approach 1:
The patent extracts and eliminates the complicated sample preparation steps from the DNA data storage process. Instead of requiring amplification, cloning, or population-based methods, the system directly reads information from individual DNA molecules using processive enzymes, simplifying the workflow while maintaining high information density.
Solution Approach 2:
The processive enzymes naturally process individual DNA molecules as they move along the strand, performing the reading function without requiring external amplification or copying steps. The enzymatic process itself serves the data extraction need directly from the stored DNA, eliminating the need for complex preparatory procedures.
3Productivity
If processive enzyme sensors are used to read DNA data, then fast data extraction is achieved, but the sensor system complexity increases
Solution Approach 1:
The patent uses processive enzymes as intermediary molecules that bridge the gap between stored DNA data and detectable signals. These enzymes naturally process DNA while generating measurable outputs (such as fluorescence or electrical signals), serving as both the reading mechanism and signal generator, which manages system complexity while maintaining high extraction rates.
