Go with the flow: Laser-induced flow patterns are used to direct the self-assembly of dissolved inorganic polyoxometalate clusters into robust, hollow tubular networks and micro-materials (see picture; scale bar: 500 μm) in real time. The hollow nature of these materials can be exploited to develop devices in which the self-assembled tubes act as microscopic flow channels.
