Theoretical and practical aspects of employing nanometrological equipment to characterise the physical properties of nanomaterials, nanostructures, nanodevices, and nano systems are all covered under nano characterization. Nanoparticle characterization is a subfield of nanometrology concerned with identifying and measuring the physical and chemical properties of nanoparticles. Nanoparticles are often designed for their unique properties and have at least one exterior dimension of fewer than 100 nanometres. Nano characterization is used for a variety of purposes, including occupational exposure evaluations to determine health and safety issues, nanotoxicology research, and process control. Characterization is a basic way for evaluating materials obtained from bottom-up or top-down procedures. This characterisation can be accomplished using a wide range of scientific methodologies. Characterization illustrates the peculiarities of nanomaterials' composition and structure, which will serve as a guide for specific preparation, property evaluation, and use of these materials.
Nanomanufacturing is the term for manufacturing at the nanoscale. Nanomanufacturing is a set of industrial techniques that use nanotechnology to create things at the nanoscale. Nanoscale materials range in size from one to 100 nanometres, with one nanometre equalling one billionth of a meter. Nanomanufacturing is the process of producing nanoscale materials, structures, devices, and systems in a scaled-up, dependable, and cost-effective manner. It also comprises top-down and more complicated bottom-up or self-assembly process research, development, and integration. Nanomanufacturing, to put it another way, results in the creation of better materials and innovative products.
