| Nanoscience offers the promise of producing revolutionary advances in many areas of technology, ranging from electronics and computing to biology and medicine, yet the realization of this promise will depend critically on addressing fundamental scientific issues surrounding the materials, surfaces and assembly. This presentation will provide an overview of key results addressing fundamental issues and hurdles along pathways to integrated nanosystems based on nanowires. First, the reproducible growth and transport properties of nanowires with controlled electrical properties will be discussed, with a particular emphasis on unique advantages of radial heterostructures for controlling active surfaces and enhancing function and performance. Second, flexible strategies for the fabrication of highly integrated structures on both traditional and plastic substrates will be described with an emphasis on controlled assembly enabled through modification of surface properties. Third, examples of state-of-the-art integrated nanowire systems will be described including electrically-based multiplexed biosensors and multi-functional electronics. Scientific challenges that must be addressed to push these and other integrated nanowire-enabled systems to true technologies in the future will be summarized. |
