Biomimetic Platform To Rapidly and Accurately Uncover Blood Clotting Abnormalities

Our Innovation

FloBio’s innovative approach brings the power of microfluidics to the bedside and creates a biomimetic platform that simulates and visualizes clot formation. The current platform is designed to directly measure blood clotting function components and the entire clotting process.

Our platform technology will include a fully automated table-top analyzer and a proprietary disposable microfluidic device that evaluates the patient’s blood biology in real-time, under physiological and dynamic flow conditions.

We are designing a system that:

  • Is simple and easy to use and interpret
  • Uses a small volume of blood (<250 uL)
  • Uses multiplex detection of clotting abnormalities
  • Provides rapid beside, point-of-care analysis and results

This near patient diagnostic platform can help to personalize patient care by rapidly evaluating bleeding and thrombotic risk within 10 minutes. The results inform therapy choice and provide insight into drug activity and reversal, as well as the ability to monitor effectiveness.

Proven Science and Versatile Platform

Our technology is based on more than 10 years of research with more than 30 related publications, demonstrating the scientific proof of concept across a broad range of clinical and pharmacologic applications where understanding bleeding and clotting risk is essential.  Our versatile R&D pipeline includes tests for anticoagulation drug activity, trauma-induced coagulopathy and neonate applications.

Our 1st Test In Development

Blood thinner medications and related adverse drug events have been a leading reason for emergency department visits costing hospitals $2.5B annually.  With the advent of newer blood thinners or direct oral anticoagulants (DOACs) over the last ten years, there has been increasing focus on their safe use in certain clinical situations and the need for a DOAC specific test to assess anticoagulation levels.

Our first test addresses the growing need for Direct Oral Anticoagulant (DOAC) testing. Today, DOACs can not be easily monitored, presenting diagnostic challenges for clinicians when faced with bleeding concerns and managing emergent critical patients.  Our initial test will be the first of its kind to provide information on blood clotting function and DOAC status to improve clinical decision-making and drive cost-effective treatment.
