Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for measuring HbA1c and other glycated substances using oxidases require high enzyme concentrations and prolonged reaction times, limiting efficiency and sensitivity.
Innovation Solution
A compound represented by the formula R1—N═N—R2, where R1 and R2 are aromatic rings or heterocyclic rings with specific substituents, is used as an oxidase reaction accelerating agent to enhance the enzymatic reaction catalyzed by oxidases such as amadoriase, sarcosine oxidase, and cholesterol oxidase, reducing enzyme requirements and shortening reaction times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high concentrations of oxidase enzymes are used to complete the reaction in short time, then reaction speed is improved, but cost increases due to expensive enzymes
Solution Approach 1:
The patent introduces a reaction accelerator compound as an intermediary substance that mediates between the substrate and oxidase enzyme. This compound enhances the enzymatic reaction rate by facilitating the conversion process, allowing the system to achieve high reaction speeds without requiring proportionally high enzyme concentrations, thus resolving the contradiction between speed and enzyme quantity
Solution Approach 2:
The patent changes the chemical parameters of the reaction system by introducing a specific compound (reaction accelerator) that modifies the reaction kinetics. This parameter change enables the system to operate at optimal enzyme concentrations while achieving the desired reaction completion time, balancing both speed and enzyme usage
2Loss of time
If high concentrations of oxidase enzymes are used, then reaction completion time is reduced, but measurement cost increases
Solution Approach 1:
The reaction accelerator compound serves as a mediator that enhances the efficiency of enzyme-substrate interaction. By introducing this intermediary, the system achieves rapid reaction completion without the need to use excessive amounts of expensive enzymes, thus resolving the contradiction between time efficiency and enzyme consumption
Solution Approach 2:
The patent employs a small-molecule reaction accelerator compound that can be used in relatively high concentrations compared to the expensive enzyme. This cheaper substance compensates for the enzyme's limited availability and high cost, enabling rapid reactions without requiring large amounts of the expensive enzymatic catalyst
