Nanotechnology is the new field of technological innovation on their application in human biology and medicine. On the other hand, there is an important concern about the potential health and environmental risks, due to exposure to human body of nanoparticles. These nanoparticles led to the appearance in the scientific disciplines such as nanotoxicology and nanomedicine.  Nanotoxicology is the study toxicity effects of nanoparticles on human health as well as environment. Nano-particles have been developed for beneficial studies with applications in medical field and devices. Also, nanomedicines have been applied to the sector of molecular biology, tissue culture, bio-materials, genetic engineering, bio and bio-imaging sensors. Actually, nanotechnologies have followed healthcare improvements including potentially revolutionary treatments for cancer, critical diseases and also drug improvements with reduction of side effect. With all these descriptions, the extent of potential impact on human health is still a major concern due to lack of reliable toxicity data of nanoparticles. The main purpose of present literature is providing of better understanding on nanobiotechnology principles and its applications in biomedicine have been discussed as well as to their side effects.
