Active Control of Transport in Molecular Assemblies

伊利诺伊大学的Paul Bohn教授得到了分析和表面化学计划的支持，以研究含有金属纳米颗粒的纳米级聚合物薄膜中的电位梯度。 PI在丙烯酸酯基聚合物（水凝胶）中建立平面内电位梯度，以控制凝胶的化学和物理性质。正在研究与流体介质中分析物的相互作用（如配体结合）。 该提案包括表面等离子体共振生物传感，电化学，有机薄膜，界面聚合，以及改变和询问表面特性的多功能方法。受控的分析表面，如这些建议可以受益于化学成像，传感器和分离，以及芯片实验室应用等领域。在生物学中也有应用，即细胞粘附和迁移的研究。 参加克拉克亚特兰大大学暑期项目的高中生参与了这项研究。

Professor Paul Bohn of the University of Illinois is supported by the Analytical and Surface Chemistry program to investigate potential gradients in nanometer-scale polymer films containing metallic nanoparticles. The PI is building in-plane potential gradients in acrylate-based polymers (hydrogels) to control the chemical and physical properties of the gel. Interactions with analytes (such as ligand binding)in a fluid medium are being studied. The proposal includes surface plasmon resonance biosensing, electrochemistry, organic thin films, interfacial polymerization, and versatile methods to alter and interrogate surface properties. Controlled analytical surfaces such as these proposed could benefit areas such as chemical imaging, sensors and separations, and lab-on-a-chip applications. There would also be applications in biology, namely, the study of cellular adhesion and migration. High school students involved in a summer program at Clark Atlanta University participate in the research.
