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至微米长度尺度上横向结构化。纳米结构在表面上的空间定向组装和表面的图案化是越来越感兴趣的主题，因为它是电子器件小型化的持续进展和新的纳米级器件概念的发展的核心。目前的自上而下的光刻和印刷方法各自在成本和可达性、横向特征尺寸、并行制造能力（生产量）或可被图案化的材料类型方面具有限制。因此，真实的需要允许纳米至微米尺寸特征的简单大规模图案化的替代方法。我们正在解决这一需求，通过使用的朗缪尔-布洛杰特膜沉积技术，立体和化学选择性酶的表面转化，和电荷转移相互作用，组装两亲性分子（磷脂，离子表面活性剂，聚电解质）和纳米粒子在固/液界面在一个控制的方式。在发现补助金的时间框架内进行的研究预计将在纳米纤维，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.
