Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods are inadequate for accurately diagnosing and treating nongonococcal urethritis (NGU) and assessing the risk of human immunodeficiency virus (HIV) infections based on the genitourinary microbiome, as the relationships between bacterial species and these conditions are not well understood.
Innovation Solution
The development of kits and methods that detect and classify NGU and HIV infections by identifying specific pathogens in urethral and vaginal samples using PCR and probe hybridization techniques, allowing for targeted therapeutic interventions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If PCR and probe hybridization techniques are used to detect specific pathogens, then measurement precision of pathogen detection is improved, but device complexity increases
Solution Approach 1:
The detection system is segmented into distinct functional modules: PCR amplification module with specific primers for target pathogens, probe hybridization module with fluorescently labeled probes, and detection module. Each module performs a specific function, allowing for optimized performance while managing complexity through modular design.
Solution Approach 2:
Fluorescently labeled probes serve as intermediaries between the amplified pathogen DNA and the detection system. The probes specifically bind to target sequences and emit fluorescent signals that can be detected, thereby translating molecular recognition into measurable signals with high precision.
2Adaptability or versatility
If multiple pathogens are detected simultaneously, then adaptability of the diagnostic system is improved, but manufacturing precision requirements increase
Solution Approach 1:
The diagnostic kit is designed with universal functionality to detect multiple pathogens including N. gonorrhoeae, C. trachomatis, M. genitalium, and other urogenital pathogens simultaneously. The system uses a panel of pathogen-specific primers and probes that can be applied in a single PCR reaction, enabling multi-pathogen detection with a unified platform.
Solution Approach 2:
Each primer and probe in the multiplex system is designed with high local specificity to its target pathogen sequence. The primers and probes have optimized binding characteristics for their respective targets, allowing specific amplification and detection of each pathogen even in the presence of multiple pathogens and complex sample matrices.
3Reliability
If comprehensive microbiome analysis is performed, then reliability of infection risk assessment is improved, but loss of time in processing increases
Solution Approach 1:
The system performs preliminary amplification of pathogen-specific DNA sequences using PCR before detection. This preliminary action concentrates and enriches the target analytes from complex microbiome samples, enabling reliable detection of low-abundance pathogens and improving the reliability of infection risk assessment while managing processing time through efficient amplification protocols.
Solution Approach 2:
The system replaces traditional culture-based methods and manual examination with automated PCR amplification and fluorescent probe detection. This substitution of mechanical and manual processes with automated molecular biology techniques reduces processing time while maintaining or improving the reliability of infection risk assessment through objective, quantifiable results.
