Biosensor Detects HER-2 Breast Cancer in 15 Minutes
January 22, 2019 | Terry Sharrer
University scientists in Connecticut have built a microfluidics device that can determine HER-2 blood markers in 15 minutes. “The [inkjet] printed chip, consisting of an array of electrodes, was deposited into a pre-fabricated microfluidic device that regulates fluids to flow in a controlled manner. During the test process, a patient’s blood sample flows through the microfluidic device and the biosensor chip coated with antibodies, which then captures and immobilises HER-2 proteins present in the sample. Abnormal levels of HER-2 is considered to be an indicator of a specific type of breast cancer, and its detection is expected to enable treatment strategies.” MORE
