The combination of remarkable mechanical properties and unique electronic properties of carbon nanotubes(CNTs) offers significant potential for revolutionary applications in electronics devices, computing and data storage technology, sensors, detectors, nanoelectromechanical systems(NEMS), as tip in scanning probe microscopy(SPM) for imaging and nanolithography and a number of other applications. Thus the CNT synthesis, characterization and applications touch upon all disciplines of science and engineering. This tutorial will provide an overview of the following topics: CNT properties, growth techniques particularly CVD and plasma CVD, patterned growth, vertical alignment, challenges in controlling the diameter and chirality as well as scaleup issues, characterization, applications in nanoelectronics, sensors, field emission, microscopy and others.

Nanorobotics encompasses: (i) design and fabrication of nanorobots with overal dimensions at or below the micrometer range and made of nanoscopic components; (ii) programming and coordination of large numbers of nanorobots; and (iii) programmable assembly of nanoscale components, either by manipulation with micro or macro devices, or by directed self-assembly.
The tutorial begins by discussing nanorobot construction. The emphasis is on nanomachines, an area which has seen a spate of rapid progress over the last few years. Nanorobots are quintessential NEMS (nanoelectromechanical systems) and raise all the important issues that must be addressed in NEMS design: sensing, actuation, control, communications, power, and interfacing across spatial scales and between the organic/inorganic and biotic/abiotic realms. Nanorobots are expected to have revolutionary applications in such areas as environmental monitoring and health care.
The tutorial's focus then changes to nanoassembly by manipulation with SPMs (Scanning Probe Microscopes), which is a relatively well established process for prototyping nanosystems. Experimental results are presented which show that interactive SPM manipulation can be used to accurately and reliably position molecular-sized components. These can then be linked by chemical or physical means to form subassemblies, which in turn can be further manipulated. Applications in building wires, single-electron transistors and nanowaveguides are presented. Finally, we discuss an emerging paradigm in self-assembly, in which active elements (nanorobots) are used to build nanostructures.

The past decade has witnessed significant progress in nanostructures and nanoelectronics. This tutorial will focus on nanoelectronics based on one-dimensional nanostructures, including inorganic nanowires, molecular wires, and carbon nanotubes. The synthesis of these fascinating materials will be reviewed, with particular attention paid to the vapor-liquid-solid approach for nanowires. In addition, nanoelectronics based on such nanostructures will be discussed in detail, including nanoscale transistors, molecular memory devices, magnetoresistive devices, optoelectronic devices, and integrated logic circuits. Future directions in various emerging fields will also be discussed.
