Using Inkjet Printers to Build a New Biosensor for Less Invasive Breast Cancer Detection

Researchers at the National Institute of Biomedical Imaging and Bioengineering (NBIB) have created a novel, low-cost biosensor to detect Human Epidermal Growth Factor Receptor 2 (HER-2), a breast cancer biomarker in the blood, allowing for a far less invasive diagnostic test than the current practice, a needle biopsy. The scientists combined microfluidic technology with diagnostics, including electrochemical sensors and biomarkers, into a powerful package that can give results in about 15 minutes.
