Stanford Researchers Develop Magnetic Wire that Increases Detection of Circulating Tumor Cells
July 16, 2018
In a study published online July 16 in Nature Biomedical Engineering, the Gambhir Lab has developed a technique to use a magnetized wire to attract circulating tumor cells (CTCs) labeled with magnetic nanoparticles. This technique, which has only been used in pigs so far, attracts from 10-80 times more tumor cells than current blood-based cancer-detection methods, making it a potent tool to catch the disease earlier. It can also serve a general strategy to sample the entire human blood volume and catch many different kinds of rare circulating blood biomarkers.
