Nanoscience is the science at the nanoscale, where ‘nano’ refers to processes that occur on the size range between 1 and 100 nm. At this length scale, material properties can be dominated by size-dependent features, such as quantum confinement and surface plasmon resonance.

In simple terms, within the nanoscale materials (nanomaterials) can behave in novel and unexpected ways. Additionally, due to their very small size, the surface area of nanomaterials is exceptionally high, a feature that also influences their properties enormously, and leads to high reactivity, and a large area for binding of biomolecules and other environmental compounds. These properties can be exploited for a diverse range of applications relevant to environmental and human health. Examples include environmental remediation and the sensing and controlled delivery or chemicals to the environment (e.g., crops) and drugs to humans.

Processes at the nanoscale have also been linked to adverse outcomes on human and environmental health. It is possible that the very same physicochemical properties that give nanomaterials their unique behaviour may turn them into hazardous substances, due to, for example, their ability to cross biological barriers or induce fast release of a toxic cargo.
