Microspheres: Tiny Particles Creating Big Possibilities
Microspheres are microscopic, spherical particles that have quietly become essential in science, engineering, and medicine. Although invisible to the naked eye, they can dramatically influence how materials behave, how drugs are delivered, and how technologies evolve. Their impact is wide-ranging because their structure—perfectly round and extremely small—allows them to interact with environments in remarkable ways.
At their core, microspheres are typically made from materials such as glass, polymers, ceramic, or even biodegradable substances. The choice of material gives them specific properties, like buoyancy, softness, durability, or the ability to break down inside the human body. Because of this flexibility, researchers and industries use them in everything from lightweight composites to advanced medical treatments.
One of the most fascinating roles of microspheres is in medicine. Biodegradable polymer microspheres are used to deliver drugs slowly and precisely within the body. Instead of taking multiple doses of…
