Researchers from Sandia National Laboratories, the University of New Mexico, and the University of Georgia, all in the U.S., have developed a method for producing nanoscale porous hollow platinum spheres, or nanocages, that may have biomedical, catalytic, and optical applications. The article says that previous methods for producing these nanocages had low yields and poor stability. The article says that the new method involves placing liposomes in a platinum salt solution and then irradiating the liposomes in order to grow the nanocages.
