Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for identifying unknown or emerging pathogens are inadequate, particularly for rapidly evolving viruses and biological threats, as they rely on culturing and traditional phenotypic characterization, which is time-consuming and inefficient, especially when dealing with viruses that cannot be cultured.
Innovation Solution
A method involving the creation of ordered emulsions with microdroplets to isolate, sort, and analyze pathogens, allowing for rapid genome and proteome identification by encapsulating organisms in discrete microdroplets for parallel analysis and amplification, enabling faster detection and characterization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional culturing and phenotypic characterization methods are used for pathogen identification, then comprehensive characterization can be achieved, but the process is time-consuming and inefficient
Solution Approach 1:
The patent segments the pathogen identification process into multiple parallel microdroplet reactions, each containing specific reagents for different detection targets. This allows simultaneous analysis of multiple pathogens and genetic markers without sequential processing, dramatically reducing identification time while maintaining comprehensive characterization capability
Solution Approach 2:
The patent performs preliminary actions by pre-loading microdroplets with specific reagents, primers, and enzymes before sample introduction. This pre-preparation enables immediate reaction upon pathogen detection, eliminating the need for time-consuming setup during the identification process and accelerating overall turnaround time
2Productivity
If microdroplet emulsion technology is used for pathogen isolation and analysis, then detection speed and sensitivity are improved, but device complexity increases
Solution Approach 1:
The patent employs self-service mechanisms where microdroplets automatically form, separate, and react based on their physical and chemical properties without requiring complex external control systems. The emulsion technology leverages natural phase separation and surface tension effects to achieve droplet manipulation, reducing the need for sophisticated actuation mechanisms
Solution Approach 2:
The patent designs a universal microdroplet platform that can handle multiple detection functions using the same basic technology. The same microdroplet generation and handling system can detect different pathogens, perform various amplification reactions, and conduct multiple types of analysis simultaneously, reducing overall system complexity through functional integration
3Quantity of substance
If samples are analyzed in bulk without partitioning, then processing is simpler, but detection sensitivity for low-concentration pathogens decreases
Solution Approach 1:
The patent segments the bulk sample into numerous individual microdroplets, each containing a small volume of sample and reagents. This segmentation concentrates potential pathogen targets within discrete droplets, increasing the probability of detection for low-concentration pathogens while maintaining high throughput through parallel processing of many droplets
Solution Approach 2:
The patent changes the physical parameters of the sample by transitioning from bulk liquid phase to dispersed microdroplet phase. This parameter change increases the surface area-to-volume ratio, enhances reagent accessibility, and concentrates analytes within each droplet, thereby improving detection sensitivity without sacrificing overall sample processing capacity
