NANO BUBBLES: CONCEPT & RECENT ADVANCES AS THERAPEUTIC AGENT

Micro/nanobubbles (MNBs) refer to structures that have a core separated from the periphery and is composed of gas. They are sized at the micro or nano level . The shell of an MNB distinguishes the external environment and the core that includes gases or drugs therein . These bubbles not only serve as transporters that deliver gases or drugs into the body but also act as contrast agents by contrasting vibration patterns of surrounding tissues with blood vessels by ultrasound. nanobubbles are less affected by changes in volume concentration than microbubbles . Cavitation, which is one of the characteristics of bubbles in an ultrasonic field, allows them to be used as an ultrasonic contrast medium. The Present Review Focus The various advantages of Nano Bubbles when utilised and Designed for Therapeutic Purposes.
