The Creation of Integrated Devices with Nanostructured Materials

Research in our group is focused on the fabrication of novel nanostructured materials using a variety of existing and emerging techniques. We also investigate how to integrate these materials into devices for a number of possible applications ranging from disease detection to energy management. In the past, we have developed a method to make large arrays of nanocolumns with controlled size, aspect ratio, and intercolumn spacing (Figure 1). The excellent controllability and tunability of this unique method enables the use of these materials in a wide range of integrated devices. For instance, one of our on-going research projects is to establish a platform for the integration of on-chip handling, separation, and the detection of biomarkers using this integrated nanocolumn array platform. Another major research direction is to use such nanostructured materials for the efficient generation and conversion of energy. Other than these, we are interested in novel mechanisms for molecular sensing and manipulation. The research in this direction could greatly extend our capabilities to handle difficult problems in real applications, for instance, the detection of low profile cells in a huge background. In a current project, we are developing a method to adaptively sense and recognize chemical and biological molecules (Figure 2). To achieve our goals, we utilize state-of-the-art electronic and optoelectronic measurement systems as well as material synthesis and processing equipment.
