Circulating Diseased Cell Detection via Marker Profile Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current diagnostic methods rely on population-derived average values, making them inadequate for early and personalized detection of diseases, as they fail to account for individual variations in marker expression levels.
Innovation Solution
A method involving the comparison of marker profiles between circulating diseased cells and control cells or bodily fluids to identify disease-specific markers, enhancing specificity, sensitivity, and accuracy by enriching the signal of disease-associated markers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If population-derived average values are used for diagnosis, then general applicability is improved, but measurement precision deteriorates due to individual variations in marker expression levels
Solution Approach 1:
The patent segments the blood sample into distinct cell populations (diseased cells vs. control cells) and analyzes marker expression in each population separately. This segmentation allows for personalized diagnosis by comparing disease-specific marker profiles within the individual's own sample, eliminating the need for population-derived averages while maintaining detection accuracy.
Solution Approach 2:
The patent extracts and isolates circulating diseased cells from the patient's blood sample, separating them from control cells. This extraction enables focused analysis of disease-specific markers in the diseased cell population, improving measurement precision by eliminating confounding variations from healthy cells and population averages.
2Measurement precision
If circulating diseased cells are analyzed, then detection sensitivity is improved, but device complexity increases due to cell isolation and profiling requirements
Solution Approach 1:
The patent employs antibodies that specifically bind to disease-associated markers on circulating diseased cells, enabling self-sorting and isolation of the target cells. This self-service approach simplifies the isolation process by leveraging the cells' own marker expression to facilitate their separation and enrichment, reducing the need for complex external sorting mechanisms.
Solution Approach 2:
The patent utilizes fluorescently labeled antibodies that bind to disease-specific markers, causing diseased cells to exhibit fluorescent signals. This color/fluorescence change enables easy identification, separation, and enrichment of circulating diseased cells from control cells, simplifying the analysis process while maintaining high detection sensitivity.
