Rapid diagnostic tests based on paper microfluidics

Paperdrop Diagnostics S.L. develops rapid diagnostic tests based on paper microfluidics, dealing with non-covered medical needs and emerging health problems, with special interest in critical and prevalent diseases. Our technology is based on lateral flow immunoassays, similar to pregnancy tests, which are being optimized to act as a clinical decision tool. A single drop of patient’s fluid (e.g. blood) is required to carry out the test using a paper sensor. It is a low-cost and easy-to-use tool that presents improved sensitivity and specificity than current lab tests.

Equipment-free

No need of any equipment, just a device as simple as a pregnancy test and one drop of sample.

Ultrasensitivity

Molecular and genetic biomarkers along with new signal detection and visualization strategies.

Low cost

Paper has unlimited capacities, is easy to be manufactured and is totally reciclable.

Fast & Easy

Just one drop on the paper, wait about 5 minutes and that’s it: the diagnostic is done.

Our process

PHASE I

Biomarker selection
Biomarker selection
The clinically promising biomarkers are deployed to obtain the most effective and affordable solution for practitioners and patients on paper-based tests.
Bioreceptor implementation
Bioreceptor implementation
The most sensitive receptors for target biomarkers are identified, adapted and implemented through cutting-edge nanotechnology.
Signal enhancing
Signal enhancing
Ultrasensitivity is achieved through new signaling strategies and with the use of nanoparticles, nanomaterials and fitted chemistry.
Try on samples
Try on samples
The paper-based diagnostic test is implemented using synthetic samples optimizing the analytical performance and then consolidated on real samples.
Minimum Viable Product

The proper certifications for manufacturing, commercial distribution and the use for diagnosis are obtained for the target markets.
Regulatory agency approval
Regulatory agency approval
Approval application through the clinical evidence of usability and the conformity with its applicable requirements of safety and performance.
OUR FIRST PRODUCT

Ischemic stroke risk test

Strokes are the second leading cause of death in the world, according to the American Stroke Association. 87 % of strokes are caused by a blood clot, a plaque buildup, or a combination of these two things, being known as ischemic strokes. The other type of strokes, known as hemorrhagic strokes, happen when a blood vessel in or around the brain becomes weak and ruptures.

With just a single drop of blood, now we can predict the risk of suffering from an ischemic stroke.
