Nanotechnology offers the promise of producing revolutionary advances in many areas of technology, ranging from electronics and computing to biology and medicine, and thus may impact in a substantial way our future lives. This presentation will provide an overview to the bottomup paradigm for nanotechnology enabled using nanowire building blocks. First, the growth of nanowires, with composition controlled down to the atomic scale, their fundamental electronic properties, and the assembly of integrated structures will be described. Second, nanowire devices configured as electricallybased biosensors will be discussed with an emphasis on disease detection and the ultimate sensitivity limits. Third, the potential of these studies to impact other areas of science and technology will also be described highlighting nanocomputing and its linkage to biological information processing, and electricallybased nanophotonic sources and detectors. Challenges and goals that must be met to realize these and other nanotechnologies in the future will be discussed.
