Hollow nanostructures are functional structures suitable for high energy material storage, controlled drug release, light weight structural materials, catalysts and filters. We present evidence, based on scanning and transmission electron microscopy measurements, for the formation of one and three dimensional hollow nanostructures from chemically modified silver particles. One dimensional structures form in acid media while an increase in the solution ionic strength result in the formation of hollow nanostructures that exhibit three dimensional order. Such structures can find applications in high energy material storage, catalysis, electrochemistry and biomedicine.
