Microparticle

Note 1: The lower limit between micro- and nano-sizing is still a matter of debate.Microparticles are particles between 1 and 1000 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. Microparticles are particles between 1 and 1000 μm in size.
