From a synthesis standpoint, nanotechnologies can be classified as variations of bottom-up technologies, such as self-assembly, or top-down technologies, such as lithographic methods (Box 1). Many nanotechnologies combine aspects of both strategies.
Nanobiotechnology, bionanotechnology, and nanobiology are terms that refer to the intersection of nanotechnology and biology. Given that the subject is one that has only emerged very recently, bionanotechnology and nanobiotechnology serve as blanket terms for various related technologies. This discipline helps to indicate the merger of biological research with various fields of nanotechnology.
