A magnetized wire was used to detect tumor cells. This could be a revolutionary method to effectively detect the early stages of cancer, according to a study from Stanford University. The wire is inserted into the vein to attract magnetic nanoparticles that cling to tumor cells in the blood. According to Science Daily, thanks to these magnetized cells, the wire can draw cells out of the bloodstream, according to descopera.ro.
The technique that has only been used in pigs currently attracts between 10 and 80 times more tumor cells than current cancer detection methods, making it a tool for early detection of cancer. Until now, Sam Gambhir, a professor at Stanford University, is focusing on the use of the tube for tumor detection, although in the future it might also be used to analyze the effectiveness of disease treatment methods.
"It could be used in any type of disease that contains cells or molecules of interest in the blood.Let's say that we are checking for a bacterial infection, the wire and the nanoparticles help to detect the infection "said Gambhir. Cells that have detached from the tumor pass through the bloodstream and can serve as indicators of the presence of cancer. Unfortunately, the reduced number of tumor cells reaching the bloodstream is not high enough that cells can be identified by current techniques.
