Nanoparticle and Nanoparticulate Film Construction in Membrane-Mimetic Systems

有机动力学项目的这笔拨款支持雪城大学芬德勒教授的膜模拟研究。这些研究集中在金属和半导体纳米粒子和薄膜的制备和表征，这些纳米粒子和薄膜在水溶液、表面活性囊泡、水单分子膜和空气-水界面上。还将研究纳米颗粒和薄膜在固体基质上的转移以及朗缪尔-布洛杰特薄膜的头基之间的结合。不同的体系将通过各种物理化学技术进行原位和非原位表征，其中包括原子力显微镜。在这个项目中，Fendler博士将进行膜模拟研究，目的是在水介质和囊泡中制备和表征金属、磁性和半导体纳米颗粒和薄膜。这些研究将为开发“湿胶体化学”方法建造先进材料提供急需和必要的信息。

This grant from the Organic Dynamics Program supports the membrane-mimetic studies of Professor Fendler at Syracuse University. The studies focus on the preparation and characterization of metallic and semiconducting nanoparticles and films in aqueous solutions, in surfactant vesicles, under aqueous monolayers, and at air-water interfaces. Studies will also be conducted on the transfer of the nanoparticles and films onto solid substrates as well as on the incorporation between headgroups of Langmuir-Blodgett films. The different systems will be characterized in and ex situ by a variety of physico-chemical techniques amongst which atomic force microscopy. In this project Dr. Fendler will conduct membrane- mimetic studies aimed at the preparation and characterization of metallic, magnetic, and semiconducting nanoparticles and films in aqueous media and vesicles. These investigations will provide the much needed and necessary information for the development of a "wet colloid-chemical" approach to the construction of advanced materials.
