Caption: Silicon mesoporous particles, aka SiMPS, about 1,000 nanometers across contain thousands of much smaller particles of iron oxide. The SiMPs can be manipulated by magnets and gather at the site of tumors, where they can be heated to kill malignant tumors or trigger the release of drugs. The particles were created by an international team led by scientists at Rice University and The Methodist Hospital Research Institute in Houston.
