Fluorocarbon and Peptide Film Growth from Polyatomic Ion Beams

这个项目题为“氟碳化合物和肽膜生长从多原子离子束”是由分析和表面化学计划的支持。 这项工作由伊利诺伊大学芝加哥分校的卢克汉利博士领导的研究小组进行，将研究使用共价键合的多原子离子束，大小为4-100个原子，用于生长光滑和纳米纹理的薄膜。 离子束允许化学官能团受控地转移到表面。 该项目包括两项相关研究。 (1)研究将在聚合物和硅表面上生长氟碳（FC）膜。 第二，肽离子束将用于在聚合物上生长生物分子薄膜。 AFM和XPS将用于表征薄膜。 这两项研究都试图确定多原子离子如何影响单个颗粒表面上的薄膜生长，重点是了解等离子体的薄膜生长，这项研究风险相对较高，但将对表面化学的基本理解产生重大影响。 特别是，它将提供离子与表面相互作用机制的细节。 离子束将被选择质量和能量。 氟碳膜可具有保护性、抗蛋白质性、透气性和/或光学性质，其在生物材料、光学、传感器和电子领域中具有应用。 这项研究的结果将引起工业界、国家实验室和表面科学领域学者的兴趣。

This project entitled "Fluorocarbon and Peptide Film Growth from Polyatomic Ion Beams" is supported by the Analytical and Surface Chemistry Program. The work, by the research group headed by Dr. Luke Hanley at the University of Illinois - Chicago, will examine the use of covalently bound, polyatomic ion beams, of the size 4-100 atoms, for the growth of smooth and nanotextured thin films. The ion beams permit the controlled transfer of chemical functionality to a surface. There are two related studies included in the project. (1) Studies will be performed on the growth of fluorocarbon (FC) films on polymers and silicon surfaces. Second, peptide ion beams will be used to grow biomolecular thin films on polymers. AFM and XPS will be used to characterize the films. Both studies seek to determine how polyatomic ions affect film growth on individual particle surfaces with an emphasis on understanding film growth from plasmas.This research is of relatively high risk but will have a significant impact on the fundamental understanding of surface chemistry. In particular, it will provide details of the mechanisms of the interactions of ions with surfaces. The ion beams will be both mass and energy selected. Fluorocarbon films can have protective, protein resistant, gas permeable and/or optical properties which have application in the areas of biomaterials, optics, sensors and electronics. The results of this research will be of interest to industry, national labs and academics working in the area of surface science.
