Nanotechnology is defined as the science and engineering involved in the design, synthesis, characterization and application of materials and devices whose smallest functional organization is at least one dimension on the nanometer scale (one-billionth of a meter). Nanotechnology is a research and technology development at atomic, molecular and macromolecular level on the scale ranging 1 - 100 nanometers. It is a newly innovated integrated science area capable of providing basic insights of phenomena of materials at nanoscale and enables creation and application of structures, devices and systems possessing novel properties unlike their bulk counterparts. Nanotechnology has also opened new applications in molecular biology, biotechnology and almost all disciplines producing new nanoscale tools beneficial of living organisms. The field has applications in disease diagnosis, treatment, drug delivery, animal nutrition, animal breeding, food production and processing companies and industries, reproduction and animal products. Representative nanomaterials presented in this review included metallic nanoparticles, quantum dots, carbon nanotubes, magnetic nanoparticles, fullerenes, liposomes and dendrimers. Though amid major innovations applied in variety of streams, yet in the early stages of its development and associated with negative environmental and public health issues. Nanotechnology is less awared publicly and poorly or none applied particularly in developing world including Ethiopia. Moreover, negative consequences are not uncommon and hence researchers and scientists are expected to indicate vividly the risks associated with nanotechnology.
