Capture Substance Complex for Test Substance Structure Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for obtaining information about the structure of test substances, such as amyloid β, in biological samples are hindered by impurities that nonspecifically bind to the glass base plate and labeled antibodies, leading to inaccurate results in pathological diagnosis and disease progression understanding.
Innovation Solution
A method involving the formation of a complex between a capture substance and the test substance, followed by selective collection and immobilization onto a base plate, where impurities are separated, allowing for accurate imaging and analysis of the test substance's structure using fluorescence or other high-resolution microscopy techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the test substance is directly immobilized on the glass base plate, then the operation is simple, but impurities and labeled antibodies nonspecifically bind to the base plate causing inaccurate measurement
Solution Approach 1:
The patent introduces a capture substance as an intermediary between the test substance and the base plate. The capture substance specifically binds to the test substance through antigen-antibody reaction, forming a complex that is then immobilized on the base plate. This mediator prevents impurities and labeled antibodies from nonspecifically binding to the base plate surface, thereby ensuring accurate measurement of test substance structure information while maintaining a relatively simple operational process.
2Measurement precision
If selective collection and purification steps are added to remove impurities, then measurement precision improves, but the process complexity and time increase
Solution Approach 1:
The patent performs preliminary action by forming the complex between the capture substance and test substance before immobilization. The capture substance is pre-mixed with the sample to form specific complexes, and then this pre-formed complex is immobilized on the base plate in a single step. This preliminary complex formation eliminates the need for subsequent purification steps to remove impurities, as the specific complex is already formed and can be directly immobilized, thereby reducing processing time while maintaining high measurement precision.
3Reliability
If a capture substance is introduced to form a complex, then specificity and measurement accuracy improve, but the device complexity increases
Solution Approach 1:
The patent introduces a capture substance as an intermediary that specifically binds to the test substance through antigen-antibody reaction. This capture substance forms a specific complex with the test substance, which is then immobilized on the base plate. The use of this specific intermediary significantly improves the reliability and specificity of test substance detection, as only the target test substance forms a stable complex with the capture substance, while impurities and non-specific substances do not bind. The increased reliability outweighs the moderate increase in reagent system complexity.
