Microparticles

Microparticles are tiny particles, often measured in micrometers (millionths of a meter), that can originate from natural sources like cells and mineral dust or from human activities such as manufacturing and pollution. They are small enough to be suspended in air, water, or biological fluids and can carry chemicals or biological materials. In healthcare, microparticles are used in drug delivery and diagnostics. Their size greatly influences how they interact with the environment or the body, affecting things like immune response, transportation of substances, and potential for health impacts, especially when inhaled or ingested.
