microburbujas

Microburbujas, also known as microbubbles, are tiny gas-filled spheres with diameters typically ranging from 1 to 100 micrometers. They are distinct from larger bubbles due to their unique physical properties and behaviors. These microscopic structures can be formed in a variety of liquids by methods such as gas sparging, sonication, or mechanical agitation. The small size of microbubbles means they possess a significantly larger surface area to volume ratio compared to macroscopic bubbles, which influences their stability and interaction with their surroundings.

The primary applications of microbubbles leverage their physical characteristics. In medical imaging, they serve as contrast agents for ultrasound diagnostics. When introduced into the bloodstream, they reflect ultrasound waves more effectively than surrounding tissues, creating a clearer image of blood flow and vascular structures. This has proven valuable in detecting and characterizing various conditions, including tumors and blood clots. Beyond diagnostics, research is exploring their use in targeted drug delivery and therapeutic applications, where their small size allows them to navigate through microvasculature and potentially deliver therapeutic agents directly to diseased areas. Their application extends to industrial processes as well, such as enhancing water treatment and promoting chemical reactions.
