Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fluorescence-based protein analysis is used to achieve high sensitivity, then detection sensitivity is improved, but protein denaturation and phototoxicity occur due to excitation light source
Solution Approach 1:
The patent replaces the optical excitation system (fluorescence microscopy with excitation light source) with a chemical reaction system. The probe compound undergoes enzymatic reaction with target proteins to produce chemiluminescence, eliminating the need for external light excitation and thereby avoiding protein denaturation and phototoxicity while maintaining high detection sensitivity
Solution Approach 2:
The patent changes the detection mechanism from fluorescence emission (requiring excitation) to chemiluminescence (self-emission through chemical reaction). This parameter change in the detection principle allows high sensitivity without the harmful effects of excitation light, as the chemical reaction directly produces light signals proportional to protein concentration
2Measurement precision
If UV absorptiometry or BCA assay is used for protein detection, then analysis can be performed, but interference from other biomolecules such as nucleic acids and phospholipids occurs
Solution Approach 1:
The patent introduces a probe compound as an intermediary that specifically interacts with target proteins through enzymatic reaction. This probe acts as a selective mediator that distinguishes target proteins from other biomolecules, preventing interference from nucleic acids, phospholipids, and other non-target substances while enabling accurate detection
Solution Approach 2:
The patent extracts the detection specificity from general protein properties (which are shared with interfering biomolecules) and focuses on enzyme-specific catalytic activity. By designing the probe to react with enzymes rather than general protein structures, the method isolates target-specific signals from background interference
3Measurement precision
If conventional protein analysis methods are used, then analysis can be performed, but complicated operations such as sample pre-treatment are required
Solution Approach 1:
The probe compound is designed to perform self-detection through enzymatic reaction with target proteins. The chemical reaction automatically produces light signals that are directly proportional to protein concentration, eliminating the need for complex pre-treatment steps such as purification, concentration adjustments, or multiple processing stages required by conventional methods
