One Platform. Infinite Diagnostic Insights.
Ricovr’s proprietary Plasmonic Fiber-Optic Absorbance Biosensor (P-FAB) is a portable, ultra-sensitive detection engine designed to identify any analyte—from drugs to hormones – with a single, non-invasive saliva sample.
The Mechanism
Ricovr’s P-FAB platform uses a U-bent optical fiber to amplify the interaction between light and target biomarkers at the sensor surface. As light travels through the bend, it creates an evanescent field that is highly sensitive to molecular binding events. This enables rapid, direct detection from saliva without the complexity of traditional laboratory workflows.
Sensitivity at Scale
P-FAB is designed to bring high-sensitivity biomarker detection out of the lab and into real-world testing environments. By combining advanced fiber-optic sensing with a portable reader and disposable cartridge format, Ricovr can deliver precise, digital results at the point of need.
- Evanescent wave interaction
- Picogram-level detection
- Wash-free strategy
Ricovr’s approach reduces the need for complex wash steps, helping simplify the testing workflow and making the technology better suited for point-of-care use.

Validated Performance:
The THC Proof Point
Ricovr’s first application, XALIVA™ THC, demonstrates the power of the P-FAB platform in one of the most challenging and urgent testing categories: recent cannabis use detection. As cannabis legalization expands, employers and safety-sensitive organizations need a better way to make timely, fair, and objective decisions.

Future-Proofing:
The Multi-Analyte Pipeline
Ricovr’s platform is designed as a scalable diagnostic engine, not a single-test product. The same core P-FAB technology can be adapted across multiple analytes and use cases by changing the assay chemistry and cartridge design.
Modular Expansion
Pipeline Verticals
- Workplace & Safety: Expanded drug panels for safety-sensitive environments, including opioids, amphetamines, and other high-priority substances.
- Clinical Diagnostics: Rapid biomarker testing for conditions where timely, accessible results can improve decision-making.
- Women’s Health: Non-invasive testing opportunities in preeclampsia, hormone monitoring, and reproductive health.
- Public Health: Point-of-care screening applications for infectious disease and community health settings.
Awards & Global Recognition
A single portable reader can support a pipeline of cartridge-based tests, allowing Ricovr to expand from THC into broader drug panels, clinical biomarkers, women’s health, and infectious disease applications.
