Abstract
Delivery of metal particles to living tissue, then applying external energy that interacts with the metal particles, is found to selectively increase the energy deposition and interaction surrounding the metal particles. The method is useful to improve treatment of various conditions, since targeted cells may be selectively altered or killed. Metal particles are also loaded into cells or membrane vesicles by placing metal seed particles into the cells or vesicles, then chemically depositing additional metal on the metal seed particles. The metal particles are useful to improve imaging and therapies by their interaction with externally applied energy.
