In materials science, a nanoparticle is a member of a class of particles (or atomic clusters), which have average dimensions smaller than roughly 100 nm. They exhibit properties not normally associated with the bulk phase of materials, such as quantum optical effects.[1]

Life sciences applications

Manufactured nanoparticles can be used for drug delivery, mimicking the behavior of cellular components and acting as "intracellular reservoirs for sustained release of encapsulated therapeutic agent" Components include:[2]

They may be manufactured as:

  • coated solid particles
  • polymers
  • solid lipid nanoparticles
