ABSTRACT
In this chapter, the author will focus on the application of nanoscale Finite-Difference Time-Domain (FDTD) in medicine with special focus in nanomedicine. Examples of reports based on this technique will be discussed. The FDTD method can be useful in several branches of science. Indeed, electromagnetic waves are all around us, and they are usually studied in several ways. In general, as already mentioned, visible light is a kind of well-known electromagnetic wave. The electromagnetic wave is an example of a nano-level phenomenon. Electromagnetic waves are all around us. The light or photon is the most basic wave that everyone knows. Light makes vision possible. As a wave, the wavelength is usually defined at the nano-level. Hence, any phenomena relating to light and other electromagnetic waves are actual topics in nanoscience. The FDTD method is a mathematically based technique that can be applied in nanomedicine. As a mathematical technique, the linkage to computational technique can be simply done.
