Portable Rapid and High Sensitivity BioSensor
(REF: S-1994) |
| Trial Project |
|
| Solution Feature |
- The solution is a multiplex ellipsometric Surface Plasmon Resonance (eSPR) sensor that simultaneously detects Legionella protein antigens and nucleic acid targets in a single test.
- Its key innovation is the use of critical coupling in periodic plasmonic arrays, which integrates amplitude and phase for ultrahigh sensitivity and stability
- The platform delivers attomole-level detection limits without any amplification step, surpassing the sensitivity of many conventional methods
- It is engineered for harsh environmental matrices and provides results within 15 minutes after a brief preconcentration step
- The technology enables a comprehensive risk assessment by quantifying genus, species, serogroup, and viability markers simultaneously with over 95% decision confidence
|
| Trial Application and Expected Outcome |
- Trials will test the sensor with real water samples to validate its performance in complex, real-world matrices
- Benchmarking the eSPR results directly against standard culture and qPCR methods will confirm its analytical accuracy and superiority
- Operating the device in a simulated field environment will assess its deployability, robustness, and ease of use for non-expert operators
- Running the full multiplex panel with all targeted biomarkers will demonstrate the successful integration of simultaneous, multi-parameter detection
- Reproducibility testing by multiple users will verify the method's reliability and readiness for technology transfer
