Microsphere

Microspheres are tiny, round balls that are so small you can't see them with your eyes alone. These balls can be made from different materials like plastics, glass, or ceramics.

Imagine you are playing with a bunch of toy marbles, but these marbles are super tiny, like the size of a sand grain. That's what a microsphere looks like.

Microspheres are often used in medical treatments to carry drugs to specific parts of the body. Think of them like mini-missiles that deliver medicine exactly where it's needed.

These tiny balls can also be used in other fields like cosmetics or even electronics. They are so small that they can fit into tiny spaces, like inside electronic circuits or in your skin pores.

In summary, microspheres are microscopic (super small) balls made from different materials. They can be used for targeted drug delivery, in cosmetics, and even in electronics.
