Fnding early stage cancer biomarkers with a new 30 times more sensitive paper-based test – Innovation Toronto

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.

Led by Wenji Dong, associate professor in the Gene and Linda Voiland School of Chemical Engineering and Bioengineering, and graduate student Shuang Guo, the researchers were able to detect miniscule levels of the cancer markers in tiny extracellular bubbles called exosomes in as little as 10 minutes. Reporting on their work in the journal, Biosensors and Bioelectronics, the researchers call the work a “significant step” in developing rapid testing and early cancer detection.

However, finding the cancer-filled exosomes in blood testing is challenging. They look the same as normal cell exosomes and other extracellular bubbles, and they are at very low levels in the blood in early cancer.

CellMax Life, a molecular diagnostics company with a proprietary technology to detect pre-cancer and cancer cells in the blood, today released further details from its U.S. study (Zenith) evaluating …
