Nanotechnology is briefly a science field searching substances having superior properties at nano-scale (different optical, mechanical and thermal properties) and those to be potentially produced in the future from these substances. Accordingly, it is a technology regarding opportunities providing the development during the formation of new products not applicable in advance and the formation of new processes. This technology that has the potential of affecting the world economy is at the development stage just now and it is thought that it will cause high changes in human life in the future 15-20 years. Nanotechnology provides an opportunity bringing new technological developments and applications appeared as impossible before as well as bringing a new perspective for available technological processes. In the context of the report in the light of mentioned information, brief information was given on the place and use of nanotechnology in fields such as systems of drug delivery, diagnosis of diseases, vaccine development, treatment of diseases, improvement of fertility functions of animals, determination of fertility capabilities of animals, store of gametes and embryos by freezing, animal breeding, farm medicine, meat and meat production, food safety, and neutralization of animals as use areas in veterinary medicine. Furthermore, in our country and the world, knowledge regarding the intended use of nano-technology based drugs used in veterinary medicine was presented in Table 1.
