Solution Overview
Problem
Current methods for detecting specific cellular states, particularly during cellular differentiation, are limited in sensitivity and specificity, especially for distinguishing between myoblasts and differentiated myotubes, and require complex measurements such as gene expression analysis.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional fluorescent probes are used for detecting cellular states, then detection sensitivity can be achieved, but specificity for distinguishing between different cell states (e.g., myoblasts vs. differentiated myotubes) is insufficient
Solution Approach 1:
The patent divides the detection system into multiple fluorescent probes, each targeting specific cellular states or differentiation markers. This segmentation allows simultaneous detection of different cell states (myoblasts vs. differentiated myotubes) with high specificity, resolving the contradiction between sensitivity and specificity by distributing detection functions across multiple specialized probes
Solution Approach 2:
The patent employs fluorescent probes with distinct emission wavelengths and excitation characteristics for different cell states. By changing the optical parameters (wavelength, intensity ratios) of the fluorescent signals, the system achieves both high sensitivity detection and specific differentiation between cell types, allowing precise measurement of cellular differentiation status
2Manufacturing precision
If complex measurement methods such as gene expression analysis are used to detect cellular differentiation, then specificity for distinguishing cell states is improved, but the complexity of the detection system increases
Solution Approach 1:
The patent replaces complex molecular biology methods (gene expression analysis requiring PCR, sequencing, etc.) with optical detection using fluorescent probes. This substitution maintains high specificity for cell state distinction while dramatically reducing system complexity, as fluorescence microscopy and flow cytometry are simpler, more direct measurements compared to molecular biology workflows
Solution Approach 2:
The patent uses fluorescent probes that emit light at different wavelengths or with different intensity ratios when bound to different cellular structures or markers. This color/fluorescence change approach provides specific cell state information through simple optical measurements, avoiding the complexity of gene expression analysis while maintaining high measurement precision
3Adaptability or versatility
If a comprehensive library of fluorescent compounds is synthesized to detect various cellular states, then the ability to detect diverse cell types is improved, but the complexity of compound synthesis and screening increases
Solution Approach 1:
The patent organizes the fluorescent compound library into systematic series based on molecular scaffolds and functional groups. This segmentation allows targeted synthesis and screening of compounds for specific detection purposes, managing the complexity of comprehensive library creation while maintaining versatility for detecting diverse cell types through modular compound design
Solution Approach 2:
The patent develops fluorescent probes with multi-functional capabilities, where single compounds can detect multiple cellular states or serve multiple detection purposes. This universality reduces the total number of compounds needed in the library, simplifying synthesis and screening complexity while maintaining broad adaptability for detecting diverse cell types through high-throughput screening
