Printed circuit board used in the saliva-based biosensor, which can detect breast cancer biomarkers from extremely small saliva samples (IMAGE)
Caption
The printed circuit board used in the saliva-based biosensor, which can detect breast cancer biomarkers from extremely small saliva samples in about five seconds, costs about $5. The design uses widely available components such as common glucose testing strips and the open-source Arduino platform.
