Animal models in cancer nanotechnology

To better understand disease processes, living organisms are still required. Animals make good research subjects since they are susceptible to many of the same health problems, may be genetically manipulated to mimic human disease conditions, and their living environment may be controlled to provide a consistent research outcome.Nanoscience studies ultrasmall structures, usually 0.1-100. nm, whereas nanotechnology is the science of manipulating these small structures. Nanoparticles are used as diagnostic and prognostic tools as well as transporters of therapeutic agents. It can provide a rapid, noninvasive tool to detect and/or treat various cancer types. In this chapter we discuss and provide examples of various nanotechnologies in animal models of cancer. The animal models of cancer provided here range from mice to dogs. This chapter does not include an exhaustive list of all possible animal models used in nanotechnology but is limited to only animal models of cancer types.
