Magnetic nanotags spot cancer in mice earlier than methods now in clinical use

e paper. "We don't have to tailor where we are looking; we can look at everything simultaneously." That produces savings in time, which, once the sensor comes into commercial use, will also translate into monetary savings.

Another virtue of the technology, Wang said, is that it uses existing technology already in use in the data storage and semiconductor industries and because of that, he added, "It can be made relatively cheaply."

"It is the same sensor you are using in a hard disk drive to read a hard disk back," he said. "Very similar to that."

One of the next steps in the research, Wang said, is to test the magneto-nano sensors on human blood samples taken from a long-term study in which researchers drew blood samples from subjects prior to any of them being diagnosed with cancer. To this end, the Stanford team will be collaborating with the Fred Hutchison Cancer Research Center in Seattle and the Canary Foundation, a nonprofit organization that focuses on early diagnosis of cancer.

"We can actually use our technology to study all these samples and we may be able to tell a year before or half a year before or three months before the diagnosis," Wang said. "That work will be extremely interesting."
