With support from the Major Research Instrumentation (MRI) Acquisition Program, the Department of Chemistry at Northern Kentucky University will acquire a Langmuir-Blodgett instrument for the creation of multilayered films. The instrument will be used to investigate 1.) dendrimer interactions with blood-brain barrier model systems; 2.) organometallic supramolecular chemistry involving fullerenes and transition metal-containing polymers; 3.) the characterization of functionalized [14]-annulenes and 4.) the physical properties of phospholipids monolayers and lipid/inhibitor interactions. A Langmuir-Blodgett instrument provides a trough with end barriers to prepare and compress monolayers of molecules and thin films several molecular layers thick. It is computer controlled to allow unsupervised deposition of uncontaminated samples. The layers are then investigated and characterized by other techniques such as spectroscopy and probe microscopy. The instrument will enhance teaching and research of undergraduates at Northern Kentucky University. It will be integrated into lab courses including the upper level instrumental course and coupled to synthetic courses where materials to be studied will be prepared.

在主要研究仪器（MRI）采购计划的支持下，北方肯塔基州大学化学系将获得用于创建多层膜的朗缪尔-布洛杰特仪器。 该仪器将用于研究1。树状聚合物与血脑屏障模型系统的相互作用; 2.）涉及富勒烯和含过渡金属的聚合物的有机金属超分子化学; 3.）官能化[14]-轮烯的表征和4.）磷脂单层的物理性质和脂质/抑制剂相互作用。 Langmuir-Blodgett仪器提供具有端部屏障的槽以制备和压缩分子的单层和几个分子层厚的薄膜。 它是由计算机控制的，可以在无人监督的情况下沉积未受污染的样品。 然后通过光谱学和探针显微镜等其他技术对这些层进行研究和表征。 该仪器将加强北方肯塔基州大学本科生的教学和研究。 它将被整合到实验室课程，包括上层器乐课程，并与合成课程相结合，在那里将准备要研究的材料。
