microparticles
Microscopic material bits
Microparticles are tiny particles typically ranging from one to one thousand micrometers in diameter—visible under a microscope but not to the naked eye.
The term appears in materials science, medicine, and environmental studies: microparticles in the bloodstream, plastic microparticles in ocean water.
In pharmaceutical contexts, microparticles serve as drug delivery systems.
Smaller particles are called nanoparticles.
