To make brain surgery easier and more effective, researchers have designed a nanometer-sized probe that can easily slip into the brain and selectively highlight tumor cells (ACS Nano, DOI: 10.1021/nn203749v).

Before surgeons excise tumors from patients’ brains, they rely on imaging techniques, such as magnetic resonance imaging (MRI), to trace the boundary between cancerous and healthy brain tissue. But distinguishing between the two tissues in the brain is tricky . . .
