Cancer "monorails" may help kill brain tumors

Scientists at Georgia Tech say they have developed a new way to treat brain cancer, one that involves tricking tumor cells to move along a microfiber "track" to a location where doctors can target them more effectively.

According to a study published in Nature Materials, the researchers constructed “monorails” thinner than a piece of human hair that mimic the pathways cancer cells normally latch on to as they spread through the brain. But the artificial pathways can instead direct the cancer cells to a location where they can be attacked by doctors.

Testing showed that brain tumors shrunk by 93 percent in animals that received these synthetic microfibers compared to tumors that went untreated. While this process offers a new potential  treatment for brain cancer, more testing is required on animals before it is attempted on humans.
