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.

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，该计划研究含有金属纳米颗粒的纳米级聚合物薄膜中的潜在梯度。PI正在以丙烯酸酯为基础的聚合物(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。在流体介质中与分析物的相互作用(如配体结合)正在研究中。该建议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性质的多种方法。所提出的受控分析表面可使化学成像、传感器和分离以及芯片实验室应用等领域受益。在生物学方面也会有应用，即细胞黏附和迁移的研究。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。
