The unique properties of nano- and mesoscale materials will be utilized to create novel smart materials for chemical sensing and for molecular separation processes. The work will be accomplished through a collaboration that involves a materials science group, a synthetic chemistry group, a bioorganic group, and a theory group, which will together conceptualize, synthesize, and utilize novel optical materials to solve problems in analytical chemistry, biology, clinical medicine, and environmental science. This project will develop new methods in materials science and synthetic chemistry, and will pursue fundamental theoretical understandings of complex chemical systems that combine mesoscale and nanoscale phenomena in complex fluids, hydrogels, and molecular recognition chemistry. This work is to be based on the intelligent polymerized crystalline colloidal array (IPCCA) materials recently developed in the labs of the PIs. The IPCCA material consists of a mesoscopically periodic array of colloidal particles polymerized into an acrylamide hydrogel.

纳米和介观材料的独特性能将被用来创造用于化学传感和分子分离过程的新型智能材料。 这项工作将通过材料科学小组、合成化学小组、生物有机小组和理论小组的合作来完成，这些小组将共同构思、合成和利用新型光学材料来解决分析化学、生物学、临床医学和环境科学中的问题。 该项目将开发材料科学和合成化学的新方法，并将追求对复杂化学系统的基本理论理解，这些系统结合了复杂流体、水凝胶和分子识别化学中的介观和纳米尺度现象。 这项工作将基于PI实验室最近开发的智能聚合晶体胶体阵列（IPCCA）材料。 IPCCA 材料由聚合成丙烯酰胺水凝胶的介观周期性胶体颗粒阵列组成。
