Characterization of nanoparticles is a branch of nanometrology concerned with the identification and measurement of nanoparticles' physical and chemical properties. Nanoparticles have at least one external dimension of less than 100 nanometers and are frequently developed for their unique features. Nanocharacterization is done for a variety of reasons, including workplace exposure assessments to assess health and safety risks, nanotoxicology research and manufacturing process control.
Nanomanufacturing is a set of industrial techniques that use nanotechnology to create products at the nanoscale. Products can be developed using one of two methods in nanomanufacturing:
