Abstract

The 21st century has seen a massive explosion in the applications of nanotechnology. These applications cover all areas of Science, Technology, Engineering, and Mathematics (STEM). The advantage of nanotechnology comes from the fact that it has revolutionized the miniaturizations of many products that are useful to the well-being of society. A typical nanotechnology application example in biomedical engineering is its usage as drug eluting interfaces for implantable devices, such as vascular stents, orthopedic implants, and dental implants. The purpose of this chapter is to discuss the various applications of nanotechnology to biomedical engineering. Some of the future nanotechnology applications in biomedical engineering include healthcare/medical, consumer medical goods, environmental, and electronics. The impact of nanotechnology applications to biomedical engineering is in many ways enabling humans to survive different ailments that otherwise could have been very difficult to manage. The safety aspects in the applications of nanotechnology to biomedical engineering are also examined.

Overview Of Nanotechnology Applications

In Nanoscience and Nanotechnologies (2004) and Knowles (2006), Nanometer, nanoscale and nanoscience are defined as follows: One thousand millionths of meter is called a Nanometer (nm). An example is that of a human hair that is about 80,000 nm wide; a red blood cell is about 7,000 nm wide; and a water molecule is about 0.3 nm wide. In the case of Nanoscale, it is the size range from 100 nm down to 0.2 nm. The study of the phenomena and manipulation of materials at atomic, molecular and macromolecular scales where properties of the materials can be quite different from those of larger scales are called Nanoscience. Nanotechnology as well as nanoscience concern very important materials called nanomaterials or nanotechnology materials.
