Abstract In the near future physical and economic constraints are expected to limit the continued miniaturisation of electronic and optical devices using current “top‐down” lithography‐based methods. Consequently, nonlithographic methods for synthesising and organising materials on the nanometre scale are required. In response to these technological needs a number of research groups are developing new supercritical fluids methodologies to synthesise and self‐assemble “building blocks” of nanomaterials, from the “bottom‐up”, into structurally complex device architectures. This concept paper highlights some of the recent advances in the synthesis of metal and semiconductor nanoparticles and nanowires by using supercritical fluids. In addition, we describe an efficient supercritical fluid approach for constructing ordered arrays of metal and semiconductor nanowires within mesoporous silica templates.
