Nanotechnology Assessment in Health Care, Risk and Its Safety

Nanotechnology, nanomedicine and nanotoxicology are complementary disciplines whose primary objective is to refine human life. Just nanomedicine offers probably the greatest potential for improving the human condition and quality of life as it plays an important role in the diagnosis and treatment of various diseases. Nanomaterials (NMs) have unique properties (size < 100 nm, a large surface area to mass ratio, an ability to bind and carry other ingredients) allowing their use in the drug delivery, imaging diagnostics and therapy. Nanoparticles (NPs) can easily pass-through biological barriers and thus can achieve a specific target, Toxicology of nanoparticles is poorly understood as there are no sufficient methods to test nanoparticles for health, safety and environmental impacts, especially in the size range lower than 50nm. Therefore, it is important to obtain information about the potential toxicity of NPs in order to avoid such a serious unwilling effect. One of the key issues of using NMs in nanomedicine is demonstration of balance between therapeutic efficacy and safety.
