Enabling Rapid, Highly-Multiplexed Test at the Home / Point of Care
Point-of-Care testing has been the Holy Grail of medical diagnostics for decades. Since the COVID-19 pandemic hit, the imperative need to develop novel capabilities that will allow for rapid, accessible, and precise immunoassay and molecular testing at any Point-of-Need, has become clear and undeniable.
Proactive Diagnostics' Q-SENS platform meets the essential criteria to fulfill this important goal:
Central lab levels of sensitivity and specificity
Results in 5-10 minutes
Minimally invasive collection of miniature fluid samples (10 μl) that enables simple self-testing
High multiplexing, allowing to probe for up to 32 biomarkers in a single run
Low cost (100-200$ device and <1$ consumable per test)
Quantitative detection, monitoring the kinetics rather than the end-point test result
Our platform technology enables the simultaneous detection of proteins, nucleic acids, and small molecules, unraveling a wide range of use-cases and possibilities. Using the Q-SENS, we aim to provide simple and accessible testing, spanning multiple novel applications.
The Q-SENS has shown exceptional performance on over 50 different assays, demonstrating its applicability toward a range of health conditions such as cardiovascular disease, infectious disease, oncology, chronic and acute inflammatory markers; and various tests in the veterinary, food safety, and dietary fields.
We envision Q-SENS becoming the platform of choice for Point-of-Need measuring of biomarkers wherever such capabilities have value.
An Enabling Technology for a Range of Applications
Q-SENS is a novel, chip-based, biosensing technology, that puts the robustness of the lab-based ELISA analyzer at the palm of one's hand while eliminating the need for any filtering or wash steps. Laser light injected into nano-scale waveguides produces detection that occurs at the intersection of two perpendicular sets of waveguides emitting the wavelength-shifted fluorescence and enabling the interrogation of specific sensing areas for the simultaneous detection of up to 32 biomarkers.
