We have developed a multiplexed microfluidic device to assess blood coagulation in the clinic or in the field. The device combines multiple tests into one, mimicking natural blood flow and ensuring safety with disposable components.  Leveraging our expertise in blood coagulopathy and microfluidics technology, we are developing and testing technology for improving the diagnosis of blood coagulation status. The device uses biomimetic principles, flowing blood through vascular-like channels that are pre-treated with specific coagulation factors. The technology will be invaluable in many clinical applications, such as trauma surgery, emergency procedures, and infectious diseases.
