Nanotechnology is the art of manipulating materials on atomic or molecular scales especially to build nanoscale structures and devices. The field is expanding quickly, and a lot of work is ongoing in the design, characterization, synthesis, and application of materials, structures, devices, and systems by controlling shape and size at nanometer scale. In the last few years, much work has been focused on the use of nanostructures toward problems of biology and medicine. In this paper, we focus on the application of various nanostructures and nanodevices in clinical diagnostics and detection of important biological molecules. The discussion starts by introducing some basic techniques of micro-/nanoscale fabrication that have enabled reproducible production of nanostructures. The prospects, benefits, and limitations of using these novel techniques in the fields of biodetection and medical diagnostics are then discussed. Finally, the challenges of mass production and acceptance of nanotechnology by the medical community are considered.
