Nanotoxicology for safe and sustainable nanotechnology.

Nanotechnology is the term given to those areas of science and engineering where the phenomena take place at nanoscale dimensions. Nanoparticles are particles with <100 nm in one dimension. They have different physical, chemical, electrical and optical properties than those that occur in bulk samples of the same material. Understanding these nanoscale properties and finding ways to engineer new...

Misinterpretation in Nanotoxicology: A Personal Perspective.

As an emerging field, nanotoxicology is gaining significant interest from scientists as well as from international regulatory firms in an attempt to build accumulated knowledge on this topic, which will be the basis for regulatory codes and safer nanotechnology. However, conflicting results and findings are abundant in the literature calling for more careful experimental design, result interpre...

Analysis of the occupational, consumer and environmental exposure to engineered nanomaterials used in 10 technology sectors.

Humans and the environment can come into contact with nanomaterials through a wide range of applications during all stages of the life cycle of nanoproducts. The aim of this commentary is to present an assessment of the potential for exposure and thus identify possible environmental, health and safety (EHS) issues for nanomaterials used in 10 technology sectors. We analysed all life cycle stage...

Nanomaterials: A challenge for toxicologists

The new and unique applications offered by nanotechnology in diverse areas have made it so popular that it is being applied today in almost all aspects of daily life. Although the small size and subsequent larger surface area of nanoparticles (NPs) endow them with some highly useful and specific properties, it also renders them more active leading to unexpected and unanticipated consequences on...
