Toxicology of nano-objects: nanoparticles, nanostrustures and nanophases

Abstract

The present paper discusses classification of nano-objects, which is based on their size, morphology and chemical nature, The subject of nanochemistry includes those nano-objects whose chemical properties depend on size and morphology, such as spheroidal molecules, anisotropic (2D) and isotropic (1D) nanoparticles, nano-clusters and nanophases. Nanophase is a nano-dimensional part of the microphase whose properties depend on its size. Yhe potential health hazards of nano-objects are associated with their capability of penetrating the body through inhalation, digestion or the skin.
