QuantiLight

QuantiLight is a MedTech company that has developed a portable blood-testing platform designed for rapid, at-home therapeutic drug monitoring. The system utilizes proprietary, patented bioluminescent sensors to analyze a single drop of blood obtained via a finger prick. A portable reader processes the sample and delivers laboratory-grade results within 15 minutes, which are then transmitted to a dedicated mobile application via Bluetooth. By moving diagnostic capabilities from centralized laboratories to the point of care, the company provides a more efficient, user-friendly alternative for frequent blood testing. This technology is rooted in research from the Department of Chemical Biology at the Max Planck Institute for Medical Research in Heidelberg, Germany, where the team pioneered the use of light-emitting enzyme-based sensors to measure drug concentrations.

The platform primarily targets the needs of chronic disease patients who require frequent medication adjustments, with an initial focus on organ transplant recipients. By enabling faster, home-based testing, the solution aims to reduce the significant time and cost burdens currently associated with standard laboratory-based diagnostic processes for both patients and healthcare providers. QuantiLight operates as a GmbH, having been officially incorporated in 2025 following a period of research and prototype development supported by the German EXIST-Forschungstransfer program. The company is actively working toward clinical validation and regulatory milestones, with a business model centered on the provision of portable diagnostic devices and recurring sales of test cartridges to streamline patient monitoring and improve therapeutic outcomes.
