A nanoparticle or ultrafine particle is a particle of matter 1 to 100 nanometres (nm) in diameter. [1] [2] The term is sometimes used for larger particles, up to 500 nm, or fibers and tubes that are less than 100 nm in only two directions. [2]: 394 At the lowest range, metal particles smaller than 1 nm are usually called atom clusters instead.
The characteristics of the nanoparticle itself plays a wide variety of roles including size, charge, composition, surface chemistry, etc. [14] Nanoparticles released into the environment can potentially interact with pre-existing contaminants, leading to cascading biological effects that are currently poorly understood.
ROS and free radical production is one of the primary mechanisms of nanoparticle toxicity; it may result in oxidative stress, inflammation, and consequent damage to proteins, membranes and DNA. [11] For example, the application of nanoparticle metal oxide with magnetic fields that modulate ROS leading to enhanced tumor growth.
The characterization of nanoparticles is a branch of nanometrology that deals with the characterization, or measurement, of the physical and chemical properties of nanoparticles.,. [1] Nanoparticles measure less than 100 nanometers in at least one of their external dimensions, and are often engineered for their unique properties. Nanoparticles ...
Upconverting nanoparticles (UCNPs) are nanoscale particles (diameter 1–100 nm) that exhibit photon upconversion. In photon upconversion, two or more incident photons of relatively low energy are absorbed and converted into one emitted photon with higher energy.
Literature reviews have been showing that release of engineered nanoparticles and incurred personal exposure can happen during different work activities. [ 17 ] [ 18 ] [ 19 ] The situation alerts regulatory bodies to necessitate prevention strategies and regulations at nanotechnology workplaces.
