ABSTRACT

The National Nanotechnology Initiative denes nanotechnology as any technology conducted or containing features at 1-100 nm. Nanodevices are systems designed on the micro-or nanoscale, with nanoscale features. When attempting to design features in the nanometer range, not only is fabrication a challenge, but verication and visualization of the results is a hurdle in itself. As this chapter will discuss, both micro-and nanoscale features offer a range of possibilities for improving medical technologies and drug delivery, but it is only with advances in fabrication technologies and analytical techniques that we are able to design, control, and characterize these features.
