The proposed research is aimed at harnessing organized, organic, molecular film assemblies to switch on, drive, and control physicochemical processes at solid/liquid interfaces in ways that will facilitate the development of nanotechnologies. More specifically, surface-confined charge-transfer interactions and enzyme reactions will be exploited for the two-dimensional assembly of (macro-)molecules and nanoparticles, and secondly, we will examine the effect of nanoparticle surface curvature on the spontaneous organization and mixing behavior of immiscible organic adsorbates. While enzyme-catalyzed reactions and organic electron-donor-acceptor compounds are well-established concepts, their application in surface chemistry, molecular assembly or nanolithography and nanofabrication is relatively new and undeveloped. Enzyme reactions and charge-transfer interactions are potentially useful tools. These offer chemically specific control over the interfacial assembly of molecules and processing of materials and can be carried out under mild conditions that are compatible with soft organic matter. The proposed research also addresses the knowledge deficit surrounding the role that nanostructure plays on the organization and miscibility of chemical groups in self-assembled monolayer films. The expected outcomes of the proposed research are redox-responsive interactions for reversibly manipulating molecules and nanoparticles at solid/liquid interfaces via electrical stimuli, enzyme-directed lithography of organic surfaces in support of nanofabrication, as well as a physicochemical understanding of molecular phase separation and miscibility in confined geometries.

拟议的研究旨在利用有组织的，有机的，分子膜组件来开启，驱动和控制固体/液体界面的物理化学过程，以促进纳米技术的发展。更具体地说，将利用表面限制的电荷转移相互作用和酶反应来利用（宏 - ）分子和纳米粒子的二维组装，其次，我们将研究纳米粒子表面曲率对自发性组织的纳米粒子表面曲率对不可分割的有机化有机化有机化剂的混合行为的影响。虽然酶催化的反应和有机电子唐型受体化合物是完善的概念，但它们在表面化学，分子组装或纳米刻痕中的应用，纳米造型相对较新且未开发。酶反应和电荷转移相互作用可能是有用的工具。这些提供了对分子界面组装和材料处理的化学特异性控制，并且可以在与软有机物兼容的轻度条件下进行。拟议的研究还涉及围绕纳米结构在组织中的组织中扮演的作用以及自组装单层膜中的混溶性的知识缺陷。拟议的研究的预期结果是通过电刺激在固体/液体界面上可逆地操纵分子和纳米颗粒的氧化还原响应性相互作用，有机表面的酶导向光刻，以支持纳米型制作的有机表面，以及对分子分离的物理学的理解，以及对分解性的理解。
