Microspheres are tiny spherical particles, typically ranging in size from 1 micrometer to 1 millimeter in diameter. They can be made from a variety of materials, including polymers, glass, ceramics, and metals, and are designed for specific applications. The unique properties of microspheres, such as their uniform size, shape, and surface characteristics, make them valuable in numerous fields.

In pharmaceuticals, microspheres are employed for controlled drug delivery. They can encapsulate active pharmaceutical ingredients, releasing them gradually over time or at specific sites within the body, improving therapeutic efficacy and reducing side effects. Their small size allows for easy administration, even through injection.

In the cosmetics industry, microspheres are used as functional additives. For instance, they can provide a smooth feel to creams and lotions, absorb oil, or scatter light to create a matte finish. In paints and coatings, they can improve scratch resistance, reduce friction, and alter the optical properties of the surface.

Microspheres also find applications in diagnostics and research. They can be used as tracers in fluid dynamics studies, as solid supports in chromatography, or as components in biosensors and diagnostic assays. The ability to functionalize their surfaces further expands their utility, allowing for specific binding of molecules or cells. Their production often involves techniques like emulsion polymerization or spray drying, which enable precise control over size and composition.
