Abstract
Description
Technical Field
[0001] This application relates to the field of DNA computing technology, and more specifically to a solid-state nucleic acid register and a method for data storage. Background Technology
[0002] In the field of modern computing, DNA computing, as an emerging computational model, has attracted widespread attention due to its unique Watson-Crick base pairing properties. This is an innovative method for information processing and computation that utilizes the chemical properties and biological reactions of DNA molecules. Its core lies in its ability to achieve complex logical operations and data storage through precise intermolecular interactions. This computational model can not only process large amounts of data in parallel but also perform efficient information processing at the microscopic scale.
[0003] The advantages of DNA computing lie primarily in its high-density storage capacity and biocompatibility. Compared to traditional electronic computers, DNA molecules can store massive amounts of information in a smaller volume, offering a new approach to solving large-scale data problems. Furthermore, DNA computing systems exhibit superior energy efficiency in certain applications because they can perform calculations at room temperature, reducing energy consumption.
[0004] In recent years, researchers have leveraged the precise molecular interactions of DNA molecules to develop a variety of functions and applications, including logic circuits, neural network computing, and medical diagnostics. These innovations demonstrate the enormous potential of DNA computing in solving complex problems, particularly in parallel processing and efficient storage. However, DNA computing also faces challenges, such as slow response times, high error rates, and insufficient system scalability. These limitations affect the practicality of existing DNA computing technologies for handling complex tasks.
[0005] At the same time, DNA computing also needs to achieve sequential computation (a crucial component of information processing), enabling the system to efficiently process and transmit information by executing instructions or operations step by step. Sequential computation is an essential part of information processing, especially in classical computers and biological systems. In biology, cells regulate complex biological processes through the sequential expression of genes, while in computer science, the operation of electronic computers also relies on the processing of sequential information.
[0006] Currently, although various DNA-based sequential computing systems have been proposed, such as timers, oscillators, and state machines, these systems still face significant limitations when performing complex numerical calculations. Existing DNA computing technologies often can only handle relatively simple logical operations and struggle to cope with higher-order, complex computational tasks. Furthermore, existing systems typically require considerable time for information transmission. For example, data reading, writing, and transmission often rely on slow chemical reactions and physical movements, which limits the breadth and practicality of their applications. Even in the context of rapid research development, effectively improving the speed and complexity of DNA computing remains a major challenge. This not only affects the theoretical applications of DNA computing but also restricts its promotion and implementation in real-world scenarios. Therefore, in-depth exploration and overcoming these limitations will play a crucial role in promoting the development of DNA computing.
[0007] In summary, existing DNA computing technologies face a series of limitations when handling complex tasks, including slow response speed, high error rate, and insufficient system scalability. This typically limits these systems to performing only relatively simple logical operations, making them ineffective at handling higher-order, complex computational tasks. Furthermore, existing sequential computing systems often consume significant time during data reading, writing, and transmission, impacting their feasibility in practical applications.

[0053] In the following description, many technical details are presented to help the reader better understand this application. However, those skilled in the art will understand that the technical solutions claimed in this application can be implemented even without these technical details and various variations and modifications based on the following embodiments.
[0054] Explanation of some concepts:
[0055] Solution-phase DNA circuits: A type of circuit system constructed using DNA molecules in a solution environment. Unlike traditional electronic circuits based on solid-state materials such as silicon, these circuits utilize DNA molecules as the primary building blocks in a liquid solution phase. Circuit functions, such as information storage, signal processing, and transmission, are achieved through interactions between DNA molecules (e.g., complementary base pairing).
[0056] Registers: Components within the Central Processing Unit (CPU), these are high-speed storage devices with limited capacity used to temporarily store instructions, data, and addresses. They act like a small "workspace" for the CPU, playing a crucial role in the computer's data processing.
[0057] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0058] This application discloses a solid-state nucleic acid register, such as Figure 1 As shown, it includes:

[0060] In this solid-state nucleic acid register design, a compact sequential digital circuit is constructed by resetting the state of the fixed solid-state nucleic acid registers, rather than physically moving them. Utilizing rewritable solid-state nucleic acid registers attached to a solid substrate, the output of a three-dimensional circuit is compressed onto a two-dimensional surface to improve information processing efficiency. After the circuit is updated, the data stored on the surface can be quickly read and transmitted to the computing system, thus enabling high-speed data transmission for sequential nucleic acid circuits.

[0062] The planar origami structure has fixed chains at specific locations on its main surface, which are used to form fixed connections with molecules on the solid support.

[0067] like Figure 2 As shown, in one application, a single solid-state nucleic acid register can have over 200 addressable storage sites. Each storage site consists of a corresponding write region, address information, and read region. By artificially designing DNA sequences, it is possible to achieve single-molecule information storage across multiple regions and sites.
[0068] like Figure 3 As shown, in one application, by combining microfluidics and manually printing different chip compartments, different DNA computation sequences and high-throughput, large-scale DNA computations can be successfully achieved.
[0069] The advantages of the solid-state nucleic acid register design in this application include:
[0070] Improved computing speed: By eliminating physical movement operations, the information transmission time is significantly shortened, thus improving the overall computing speed.

[0085] In one embodiment, step 301 further includes:
[0086] The first input nucleic acid strand of the added DNA computing circuit component is added to the solid nucleic acid reaction vessel;
[0087] After a period of reaction, the DNA computing circuit component generates the first output data with the first input nucleic acid strand, and then a strand substitution reaction is performed. The first output data is stored in the corresponding area of the solid nucleic acid register and saved as the first data strand.
[0088] Then use the reaction solution to rinse away any excess liquid.
[0089] In one embodiment, step 302 further includes:
[0090] Add a first release nucleic acid strand to the solid nucleic acid reaction vessel that already contains the calculation results;
[0091] The first data strand on the solid nucleic acid register is released into the solution through a chain substitution reaction by the first released nucleic acid strand, thus completing the reading of the first output data of the DNA computing circuit component.

[0099] Expanding computing power: This architecture can support more complex logical operations, enabling DNA computing technology to handle higher-order complex computing tasks and expanding its application scope.
[0100] Space and resource savings: By compressing the output of three-dimensional circuitry onto a two-dimensional surface, the required physical space and material consumption are reduced, thereby improving the overall efficiency of the system.
[0101] In one embodiment, the planar origami structure in the solid-state nucleic acid register is square, the solid-phase support is a glass substrate, and the solid-phase connection is formed through a binding reaction between biotin and streptavidin. Step 101 further includes:
[0102] Step 401. Multiple cube-shaped planar origami structures are constructed through base complementary pairing; the use of classic cube origami as the basic model for solid nucleic acid registers is based on the physical characteristics of various DNA origami structures that have been successfully constructed and the needs of experiments.
[0103] Step 402. Set a fixed strand at a specific position on the main surface of the planar origami structure that can hybridize with the biotin-modified support short strand, and expose the extended part of the fixed strand below the bottom surface to ensure that it can stably hybridize with the biotin-modified support short DNA strand in the future.
[0104] Step 403. Set up a read / write chain at a specific location on another main surface of the planar origami structure, exposing the extension of the read / write chain on the surface to ensure that the data chain can be stored at a specific address in a stable hybrid manner;
[0105] Step 404. Solid nucleic acid registers are obtained by annealing assembly and polyethylene glycol purification. Specifically, address-designed staple chains are mixed with backbone chains and annealed to form addressable initial solid nucleic acid registers. The DNA origami assembly process is referenced in Rothemund, PWK, Folding DNA to Create Nanoscale Shapes and Patterns. Nature 2006, 440(7082), 297–302. Before use, the assembled solid nucleic acid registers are purified by PEG, and biotin-modified supporting DNA strands and blocking DNA strands for pre-sealing storage locations are added. After incubation at room temperature for 2 hours, polyethylene glycol (PEG) purification is performed again.
[0106] In one embodiment, for ease of observation, a glass substrate is selected as the solid-phase support, and step 201 further includes:
[0107] Step 501. Clean the glass substrate using an ultrasonic cleaner and cleaning agent to remove surface contaminants: The glass substrate needs to be thoroughly cleaned using an ultrasonic cleaner with an appropriate cleaning agent (such as a mixture of deionized water and ethanol) to remove any dust, grease and other contaminants that may be present on the surface.
[0108] Step 502. Immerse the cleaned glass substrate in a sodium hydroxide solution: The cleaned glass substrate needs to be immersed in a sodium hydroxide solution for further surface activation to improve its binding ability with biomolecules.
[0109] Step 503. Dry the glass substrate activated with sodium hydroxide; incubate the treated glass substrate in a silane solution to alkylate the surface of the glass substrate.
[0110] Step 504. Dry the surface-alkylated glass substrate; wherein, after incubation, the glass substrate is gently rinsed with deionized water and dried with high-purity nitrogen. Then it is placed in a high-temperature oven to completely dry the glass substrate, and finally stored in anhydrous ethanol to ensure that no water molecules adhere to the surface of the glass substrate during the process.
[0111] In one embodiment, for ease of observation, a glass substrate is selected as the solid-phase support, and the solid-phase connection is formed through a binding reaction between biotin and streptavidin. Step 202 further includes:
[0112] Step 601. Add polyethylene glycol or biotin-polyethylene glycol solution (PEG / Biotin-PEG solution) to the glass substrate and incubate for a period of time (usually 2 hours) to allow the Biotin-PEG molecules to fully react with and fix the glass substrate surface; after incubation, rinse with the reaction solution to remove excess free PEG / Biotin-PEG molecules from the solid nucleic acid reaction tank.
[0113] Step 602. Then, add an appropriate amount of streptavidin. The streptavidin molecules can bind to the biotin molecules on the Biotin-PEG and incubate for a period of time again. Then, use the reaction solution to wash away the free excess streptavidin molecules.
[0114] Step 603. Next, add a sufficient amount of solid nucleic acid registers to the glass substrate, incubate at room temperature, and then rinse again with the reaction solution. Through the above steps, the solid nucleic acid registers are fixed on the glass substrate, and the solid nucleic acid reaction tank is completed, which can provide a stable and controllable reaction environment.
[0115] In one embodiment, a read / write chain is provided at a specific location on a main surface of the planar origami structure, and step 103 further includes:
