"Rapid Saliva-Based Breast Cancer Detection Device Unveiled"
Researchers have developed a low-cost saliva-based biosensor using disposable test strips to detect cancer-related biomarkers, such as HER2 and CA 15-3, which are indicative of various cancers including breast cancer. The test involves exposing the strips to monoclonal antibodies for the target biomarker and then measuring the resulting electrical signal changes. The experimental results matched with samples from both healthy volunteers and breast cancer patients, suggesting potential for a quick and non-invasive diagnostic method.
