Unconventional surface patterning routes

拟议的研究计划旨在开发新的方法来生产有机界面，这些界面在宏观区域的纳米到微米长度尺度上横向结构。纳米结构的空间定向组装和表面图像化是一个越来越受关注的主题，因为它是电子器件小型化的持续发展和新型纳米器件概念发展的核心。当前的自顶向下平版印刷和印刷方法在成本和可及性、横向特征尺寸、平行制造能力（吞吐量）或可图案的材料类型方面都有局限性。因此，有一个真正需要的替代方法，允许简单的大规模模式的纳米到微米尺寸的特征。我们正在通过使用Langmuir-Blodgett薄膜沉积技术、立体和化学选择性酶表面转化以及电荷转移相互作用来解决这一需求，以受控的方式在固/液界面组装两亲分子（磷脂、离子表面活性剂、聚电解质）和纳米颗粒。在发现基金的时间框架内进行的研究预计将在纳米制造、膜生物物理学、胶体化学和材料科学领域产生影响。

The proposed research program is aimed at the development of new approaches to producing organic interfaces that are laterally structured on the nanometer-to-micrometer length scales over macroscopic areas. The spatially-directed assembly of nanostructures onto and patterning of surfaces is a subject of increasing interest because it is central to the continued progression in the miniaturization of electronic devices and to the development of novel nanoscale device concepts. Current top-down lithographic and printing methods each have limitations in terms of cost and accessibility, lateral feature size, parallel fabrication capability (throughput) or the type of materials that can be patterned. There is thus a real need for alternative methods that allow simple large-scale patterning of nanometer-to-micrometer size features. We are addressing this need by using the Langmuir-Blodgett film deposition technique, stereo- and chemoselective enzymatic surface transformations, and charge transfer interactions to assemble amphiphilic molecules (phospholipids, ionic surfactants, polyelectrolytes) and nanoparticles at solid/liquid interfaces in a controlled fashion. The research carried out within the time frame of the Discovery Grant is expected to have an impact in the fields of nanofabrication, membrane biophysics, colloidal chemistry, and materials science.
