This article is published with open access at Abstract Nanotechnology has been a revolutionary thrust in recent years of development of science and technology for its broad appeal for employing a novel idea for relevant technological applications in particular and for mass-scale production and marketing as common man commodity in general. An interesting aspect of this emergent technology is that it involves scientific research community and relevant industries alike. Top-down and bottom-up approaches are two broad division of production of nanoscale materials in general. However both the approaches have their own limits as far as large-scale production and cost involved are concerned. Therefore novel new techniques are desired to be developed to optimize production and cost. Directed self-assembly seems to be a promising technique in this regard which can work as a bridge between the top-down and bottom-up approaches. This article reviews how directed self-assembly as a technique has grown up and outlines its future prospects. Keywords Nanotechnology Directed self-assembly Template assisted growth Field-induced growth Introduction Nanotechnology promises to revolutionize the way we think about but more importantly create new materials. The key to making this promise a reality is a commitment to fundamental research in critical areas including synthesis fabrication and characterization of nanoscale P.
