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.
近年来，纳米技术已成为科技发展中的一项革命性力量，因为它具有广泛的吸引力，特别是为相关技术应用引入了新颖的理念，并且总体上能够作为大众商品进行大规模生产和销售。这项新兴技术的一个有趣之处在于，它涉及科研界和相关产业。一般来说，自上而下和自下而上的方法是纳米级材料生产的两大主要类别。然而，就大规模生产和所涉及的成本而言，这两种方法都有其自身的局限性。因此，需要开发新的技术来优化生产和成本。在这方面，定向自组装似乎是一种很有前景的技术；它可以作为自上而下和自下而上方法之间的桥梁。本文回顾了定向自组装作为一种技术的发展历程，并概述了其未来前景。
