Growing Silver-Gold Nanorattles

Caption

The starting gold nanosphere seeds (left) are surrounded by a hollow, porous silver cage (middle) and become a nanorattle filled with light-scattering dyes inside a gold outer shell (right). The nanorattles can amplify and detect signals from separate types of nanoprobes without needing an expensive machine or medical professional to read the results.
