QuantiLight develops a patented bioluminescent sensor platform for rapid, at-home therapeutic drug monitoring using a fingerprick blood sample. This technology quantifies drug concentrations and biomarkers within 15 minutes, providing quantitative results comparable to laboratory standards. The system significantly reduces time-to-result and logistical burdens associated with traditional decentralized patient care.

Problem
Chronic patients, particularly organ transplant recipients, require frequent therapeutic drug monitoring (TDM) and biomarker testing, which involves costly, time‑consuming laboratory visits and logistical burdens for patients and caregivers.
Solution
QuantiLight offers a patented bioluminescent sensor platform that enables quantitative, laboratory‑grade drug and biomarker measurement from a single finger‑prick blood sample at home. The test cartridge contains engineered bioluminescent proteins that emit a color‑shifted glow proportional to analyte concentration. After inserting the cartridge into a handheld reader, the assay completes in approximately 15 minutes, and results are transmitted via Bluetooth to a mobile application for real‑time viewing and longitudinal tracking. The system supports a broad panel of small‑molecule drugs, electrolytes, proteins, enzymes, amino acids, and metabolites, providing a modular and scalable solution for decentralized therapeutic monitoring.
Target Audience
Primary users are organ transplant patients and individuals requiring regular kidney or liver function monitoring, as well as transplant physicians, nephrologists, and home‑health providers who need timely, accurate therapeutic drug data.
Features
- Engineered bioluminescent protein sensors with nanomolar limit of detection and colorimetric output readable by a simple digital camera sensor.
- Disposable test cartridge requiring only 5 µL of capillary blood, with built‑in dilution and reagent mixing for consistent assay performance.
- Hand‑held reader that performs optical detection, signal processing, and Bluetooth communication within a 15‑minute workflow.
- Mobile app that displays quantitative concentrations, stores historical data, and enables secure sharing of results with clinicians.
- Modular assay design allowing rapid adaptation to additional drugs, metabolites, and clinical biomarkers without hardware changes.
- High specificity and reproducibility validated against standard laboratory methods, meeting clinical accuracy requirements for TDM.
- End‑to‑end encryption of data transmission to ensure patient privacy and compliance with health‑information regulations.
