Solution Overview
Problem
Current methods for detecting fentanyl analogues are limited, especially in field-deployable devices, which are often costly, complex, and pose risks to operators due to hazardous reagents, and do not effectively identify a broad range of fentanyl analogues or liquid residues.
Innovation Solution
A portable test kit using a combination of chemical dyes, catalytic reagents, solvents, and surfactants in a low-cost, mass-producible format that minimizes operator exposure and provides rapid presumptive identification of fentanyl analogues and other drugs in solid, gel, or liquid residues, packaged in non-hazardous materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If commercially available FA detection devices are used, then detection capability is provided, but the devices are limited to laboratory settings and are not field-deployable
Solution Approach 1:
The detection system is divided into separate functional components: a field-deployable device section with sample application area and a laboratory analysis section with detection components. This segmentation allows the field device to be simple and portable while maintaining comprehensive detection capabilities through the laboratory section.
Solution Approach 2:
A transfer mechanism or intermediary system is introduced to move samples from the field device to the laboratory detection system. This intermediary component enables field deployability without requiring the entire detection system to be portable, resolving the contradiction between field usability and detection capability.
2Ease of operation
If field deployable detection devices are created, then portability is achieved, but operator exposure to hazardous reagents increases
Solution Approach 1:
Hazardous reagents and detection components are extracted from the field device and retained in the laboratory setting. The field device contains only safe sample collection and transfer components, eliminating operator exposure risks while maintaining field deployability.
Solution Approach 2:
Disposable sample collection devices or single-use components are employed in the field device. These disposable elements can be safely discarded after use, preventing operator exposure to contaminants and eliminating the need for complex decontamination procedures.
3Adaptability or versatility
If broad spectrum FA detection is implemented, then identification of multiple FA analogues is achieved, but false positive rate increases
Solution Approach 1:
The detection process is segmented into preliminary screening and confirmatory analysis stages. The field device performs initial screening to identify potential FAs, while the laboratory section provides confirmatory analysis with multiple verification methods, reducing false positives while maintaining broad detection capability.
Solution Approach 2:
A feedback mechanism is implemented where initial detection results trigger confirmatory tests before final identification. This multi-stage verification process with feedback loops ensures broad spectrum detection while minimizing false positives through iterative validation.
