"Microparticles" Natural Recordings by Native Speakers
Microparticles refer to extremely small particles, usually ranging in size from 0.1 to 100 micrometers (μm). These particles can be composed of various materials, such as biological molecules, chemicals, or physical matter. Microparticles can be found in various contexts, including medicine, where they might be used as a delivery system for drugs or RNA interference, as well as in industrial processes where they can be used as a carrier for pigments or other materials.
Microorganisms are tiny living things that are too small to be seen with the naked eye. They include bacteria, viruses, fungi, and other tiny organisms that can be found almost anywhere, including in soil, air, water, and even inside the human body.
