Microspheres are small spherical particles, with diameters in the micrometer range (typically 1 μm to 1000 μm (1 mm). Microspheres are sometimes referred to as spherical microparticles. In general microspheres are solid or hollow and do not have a fluid inside, as opposed to microcapsules. Microspheres can be made from various natural and synthetic materials.
