Chinese scientists build handheld cancer detector with 94.9% accuracy in trials

Researchers at Westlake University created a low-cost handheld cancer detector using a 3D BIC sensing chip and simple optics.

The device can identify cancer biomarkers from a single drop of blood and outperformed standard ELISA in 171 serum samples.

It achieved 94.9% accuracy for early detection and 92.1% for post-surgery monitoring.

The technology could make cancer screening and follow-up cheaper, faster, and more accessible outside major labs.
