Solution Overview
Problem
Current molecular data storage methods using small molecules, such as DNA or peptides, can store information stably but lack the ability to modify bits, which hinders computation and security enhancements like data protection and watermarking.
Innovation Solution
The use of thin-layer chromatography (TLC) to encode and modify messages by associating molecules with specific positions on a substrate, allowing for chemical reactions to alter the readout of molecular bits, enabling reversible and irreversible staining to change the meaning of stored data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If molecular data storage methods using small molecules are used, then information can be stored stably, but the ability to modify bits is lacking
Solution Approach 1:
The patent divides molecules into distinct subsets (first subset identifiable by first physical property, second subset identifiable by second physical property) that can be independently manipulated. This segmentation allows specific bits to be modified through selective chemical reactions while maintaining overall data stability, resolving the contradiction between stability and modifiability.
Solution Approach 2:
The patent introduces dynamic modification capability through thin-layer chromatography and chemical reactions. Molecules can be transformed from one state to another (e.g., through staining reactions), enabling bit modification while maintaining stable storage. The system transitions from static molecular storage to dynamic, modifiable storage without sacrificing stability.
2Adaptability or versatility
If thin-layer chromatography is used to modify molecular bits, then data modification and security enhancement are enabled, but system complexity increases
Solution Approach 1:
The patent replaces complex mechanical or electronic bit modification systems with chemical reactions and thin-layer chromatography. Chemical stains and reactions provide a simpler, more direct method for modifying molecular bits, reducing system complexity while maintaining modification capability and enhancing security through bit manipulation.
3Measurement precision
If multiple subsets of molecules with different physical properties are used, then unambiguous identification and encoding precision are improved, but manufacturing complexity increases
Solution Approach 1:
The patent utilizes different physical properties (parameters) of molecules to achieve unambiguous identification. By selecting molecules with distinct physical properties that can be detected through standard thin-layer chromatography methods, the patent achieves precise identification without requiring complex manufacturing processes. The approach leverages naturally occurring molecular property variations rather than engineered complexity.

AI summary
Storage media are provided. A substrate has an array of addressable locations thereon, each addressable location adapted to be physically associated with a collection of molecules, each collection comprising at least a first subcollection of molecules and a second subcollection of molecules. The molecules in the collection are selected from a set of unambiguously identifiable molecules, the set comprising at least a first subset of molecules and a second subset of molecules. Each molecule in the first subset is identifiable by a first physical property, and each molecule in the second subset is identifiable by a second physical property, different from the first physical property. Each molecule in the set is uniquely associated with a predetermined position in a numerical value, wherein the presence of the molecule in the collection indicates a predetermined digit at the associated position and the absence of said molecule in the collection indicates a zero at said associated position.
