Researchers at MIT have developed a device small enough to wear like a smartwatch but powerful enough to detect individual cells moving through the bloodstream.
The innovation, called CircTrek, was first published in the online journal npj Biosensing.
CircTrek is designed for continuous, noninvasive monitoring of circulating cells.
This real-time insight could revolutionize how physicians diagnose disease, detect relapses, assess infection risk, and monitor the effectiveness of treatments.
In clinical use, CircTrek could track whether CAR T cells remain active in patients with B-cell lymphoma, a factor linked with better treatment outcomes.
The device's Wi-Fi capability also allows for data transmission directly to a patient's care team — potentially transforming how doctors monitor patients at home.
