Abstract
Nanotechnology is a flourishing science that produces and designs materials
at the nanoscale, which ranges from 1 to 100 nanometers. They are commonly known as
nanomaterials or nanoparticles. Physical properties that characterize nanoparticles
include shape, crystal structure, and solubility properties. These properties affect the
behavior, fate, and transport, and ultimately the toxicity of nanomaterials or
nanoparticles. They are examined and assessed whether and to what degree they are a
threat to the environment or society.
