Microbubbles (/ˈmaɪ.kroʊ.bʌb.əlz/) are small gas-filled bubbles that are typically used in medical and scientific applications. They are usually less than 50 micrometers in diameter, similar in size to a red blood cell.
Etymology
The term "microbubble" is derived from the Greek word "micros" meaning small, and the English word "bubble".
Applications
