The Department of Defense (DOD) is seeking innovative solutions for the development of a portable, high-throughput handheld device designed to measure platelet contractility, which is critical for assessing platelet functional viability in transfusion settings. The objective is to create a device that can quantitatively measure clot retraction from blood or platelet-rich plasma samples, addressing current limitations in platelet function testing, particularly in military and civilian blood banking and transfusion services. This initiative is vital for improving outcomes in trauma care, as effective platelet function is essential for preventing excessive bleeding in injured patients. Interested parties should note that the solicitation is set to open on January 8, 2025, with applications due by February 5, 2025, and further details can be found at the DOD SBIR website.
