Washington State University researchers have developed a technology that is more than 30 times more sensitive than current lab-based tests in finding early stage cancer biomarkers in blood.

The technology uses an electric field to concentrate and separate cancer biomarkers onto a paper strip. It could someday become a kind of liquid biopsy and could lead to earlier detection of and faster treatments for cancer, a disease that causes more than 9.6 million deaths a year around the world.

An artist’s representation of the nanoparticle removal chip developed by researchers in Professor Michael Heller’s lab at the UC San Diego Jacobs School of Engineering. An oscillating electric field (purple arcs) separates drug-delivery nanoparticles (yellow spheres) from blood (red spheres) and pulls them towards rings surrounding the chip’s electrodes.

A new technology that uses an oscillating electric field to easily and quickly isolate drug-delivery nanoparticles from blood has been developed by a team of engineers...
