Microbubbles

Microbubbles are small gas-filled bubbles that are typically smaller than one hundredth of a millimeter in diameter, but larger than one micrometer. They are used in medical and industrial applications.

Medical Applications

Microbubbles are used in medical imaging and drug delivery. In medical imaging, they are used as a contrast agent for ultrasound imaging. They can also be used for targeted drug delivery, where they are loaded with drugs and then burst using ultrasound.

Ultrasound Imaging

In ultrasound imaging, microbubbles are used as a contrast agent. They are injected into the bloodstream and then imaged using ultrasound. The microbubbles reflect the ultrasound waves, making them visible on the ultrasound image. This can help to improve the visibility of blood vessels and other structures in the body.

Drug Delivery

Microbubbles can also be used for targeted drug delivery. They can be loaded with drugs and then injected into the bloodstream. The microbubbles can then be burst using ultrasound, releasing the drugs at a specific location in the body. This can help to improve the effectiveness of the drugs and reduce side effects.

Industrial Applications

In addition to their medical uses, microbubbles are also used in industrial applications. They are used in water treatment to remove impurities from water. They can also be used in food processing to improve the texture and taste of food.
