From Bronze Age shack to nanotechnology lab - metal forging techniques reach the bottom

The earliest forgings, appearing around 1600 BC, were crudely hammered ornaments from naturally occurring free metals. The latest, most state-of-the-art forging techniques use micron-sized hammers to forge nanometer-sized metal shapes to be used as components in nanotechnology and microtechnology systems. New research demonstrates the possibilities of nanoforging - applying conventional metal shaping techniques to nano objects. In recent years, nanoscale fabrication has developed considerably, but the fabrication of free-standing nanosize components is still a great challenge. The ability to produce high-strength metallic components with characteristic dimensions of nanometers by nanoforging opens up new possibilities to eventually produce complex microsystems by assembling free-standing nanoscopic components. At these sizes they are of the same dimensions as micro-organisms and therefore sufficiently small even to travel through the human body.
