Mikrosfääre

Mikrosfääre are tiny spherical particles, typically ranging in size from 1 micrometer to 1 millimeter in diameter. They are often hollow, although solid microspheres also exist. The term "mikrosfääre" is derived from the Greek words "mikros" meaning small and "sphaira" meaning sphere.

These particles can be made from a variety of materials, including polymers, glass, ceramics, and metals. The choice of material depends on the intended application. For example, polymer microspheres are commonly used in cosmetics and drug delivery systems due to their biocompatibility and ability to be functionalized. Glass microspheres are often employed as reflective beads in road markings and as blasting media. Ceramic microspheres find use in high-temperature applications and as reinforcing fillers.

Mikrosfääre have a wide range of applications across various industries. In the biomedical field, they are used for targeted drug delivery, diagnostic imaging, and as components in biosensors. In industry, they serve as fillers to improve the properties of plastics and coatings, as abrasives for cleaning and polishing, and as lightweight structural components. Their controlled size and spherical shape allow for predictable behavior in fluid dynamics and material formulations. The development of microspheres with specific properties, such as controlled porosity or surface chemistry, continues to expand their utility.
