Brain tumors are among the deadliest and most difficult to treat cancers. For patients with this disease, treatment usually involves open skull surgery to remove as much of the dangerous mass as possible, followed by chemotherapy or radiation, which comes with serious side effects.

Researchers at Stanford University School of Medicine have designed and tested a small wireless device in mice. The device is a remotely activated implant that can heat nanoparticles injected into a tumor, gradually killing cancer cells.

According to former Stanford University School of Medicine researcher Hamed Arami, nanoparticles will help make treatments more targeted, so there will be fewer side effects compared to chemotherapy and radiation, according to Stanford Medicine.

The researchers are now working on scaling the device for the human brain. Stanford University School of Medicine believes that with rapid progress in device development in the next five years, they will be able to develop an implant for deeper tumors.
