Microparticle
Particle with dimensions between 1 × 10−7 and 1 × 10−4 m.
Note 1: The lower limit between micro- and nano-sizing is still a matter of debate.
Note 2: To be consistent with the prefix “micro” and the range imposed by the definition,
dimensions of microparticles should be expressed in μm.
Microparticles are particles between 0.1 and 100 μm in size. Commercially available microparticles are available in a wide variety of materials, including ceramics, glass, polymers, and metals. Microparticles encountered in daily life include pollen, sand, dust, flour, and powdered sugar. The study of microparticles has been called micromeritics, although this term is not very common.
Microparticles have a much larger surface-to-volume ratio than at the macroscale, and thus their behavior can be quite different. For example, metal microparticles can be explosive in air.
Microspheres are spherical microparticles, and are used where consistent and predictable particle surface area is important.
In biological systems, a microparticle is synonymous with a microvesicle, a type of extracellular vesicle (EV).
Home pregnancy tests make use of gold microparticles. Many applications are also listed in the microsphere article.
