项目摘要

AbstractCTS-0084358J. H. Fendler, Clarkson UniversityThe objective of the proposed research is to demonstrate the possibility of continuous fabrication of nanostructures of chosen size and shape. The demonstration will be carried on self-replicating reversed micelles. It will be attempted to manufacture size-controlled monodisperse sulfide semiconductor nanoparticles and their capped counterparts in reverse micelles.The PI has acquired an extensive experience in studying the creation of nanoparticle films and multiparticulate layers on surfaces, with the help of surfactant coatings. It was observed that in such processes, man-made templates replace nature's biological membranes. Such apparent "mimicking" of biological processes has been generalized to a systematic biomimetic membrane chemistry for advanced materials preparation (e.g. colloids). The PI has explored in detail the self-replication of membrane mimetic components. The need is now to identify and control three essential biological function: compartmentalization, self-replication and self-assembly. Templates and compartments, supplemented by surfactant coating, provide the same control on the extent of a chemical transformation as a membrane would.The PI wants to generalize his research on the replication and assembly of semiconductor materials to more materials and nanogeometries. The proposed research plan is exploratory and high-risk.

摘要CTS-0084358J。H. Fendler，克拉克森大学这项研究的目的是证明连续制造选定尺寸和形状的纳米结构的可能性。演示将在自复制反胶束上进行。它将试图制造尺寸可控的单分散硫化物半导体纳米粒子和它们的封端的对应物在反胶束。PI已经获得了丰富的经验，在研究创建纳米粒子薄膜和多颗粒层的表面上，与表面活性剂涂层的帮助。据观察，在这种过程中，人造模板取代了自然界的生物膜。这种明显的“模仿”生物过程已被推广到一个系统的仿生膜化学先进的材料制备（如胶体）。 PI已经详细探索了膜模拟组件的自我复制。现在需要确定和控制三个基本的生物功能：区室化，自我复制和自我组装。模板和隔室，再加上表面活性剂涂层，可以提供与膜相同的化学转化程度控制。PI希望将他对半导体材料复制和组装的研究推广到更多材料和纳米几何学。该研究计划具有探索性和高风险性。
