UT research lab lands nearly $1 million for blood test to diagnose cancer

John Zhang at the University of Texas is using his expertise in miniaturization to help diagnose cancer where it is easy to reach but hard to detect: in the blood.

Zhang, in collaboration with researchers at UT Southwestern Medical Center at Dallas, has developed a disposable microchip the size of two thumbnails that costs about $5 and is capable of capturing as few as five cancer cells among millions of cells circulating in a person’s blood. A hand-held microscope he also invented can then read the cells and determine the type of cancer.
