Scientists Created a Device Able to Detect Cancer in a Drop of Blood

a new device to detect cancer

Researchers from the University of Kansas (KU) in Lawrence and the KU Cancer Center and KU Medical Center in Kansas City, both USA, developed an ultrasensitive device that can detect cancer in just a drop of blood.

The device is called a 3-D nanopatterned microfluidic chip. It can detect cancer markers in the smallest quantity of whole blood or in plasma by filtering for exosomes, tiny vesicles that some eukaryotic cell produce. Cancer exosomes contain biological information about tumor growth and spread.

Lead author Yong Zeng, an associate professor of chemistry at KU, comments: “Almost all mammalian cells release exosomes, so the application is not just limited to ovarian cancer or any one type of cancer. We're working with people to look at neurodegenerative diseases, breast, and colorectal cancer, for example.”
