Early Liver Cancer Diagnosis Using Magnetoresistive Biosensors

Summary

Researchers at Stanford University have developed an innovative biosensor using the giant magnetoresistive (GMR) effect to enable early, sensitive, and automated detection of hepatocellular carcinoma (HCC), the most common type of liver cancer. The biosensor leverages a magnetic-based immunoassay to detect biomarkers like alpha-fetoprotein (AFP) and C-reactive protein (CRP) in real time. It offers high accuracy, a broad dynamic range, and the ability to measure multiple targets simultaneously. Automation further simplifies the process, allowing users to control the biosensor via a smartphone app. This low-cost, portable device has the potential to improve healthcare access in resource-limited areas, enabling point-of-care testing for liver cancer and other diseases.
