Echogenic bubbles: An new avenue for cancer therapy

Abstract

The development of micro and nanobubbles as theranostics is been an emerging trend in the 21st century. Ultrasound molecular imaging is a real-time non-invasive, cost-effective, promising non-viral tool, which is been widely used in the recent times. These micro and nanobubbles are marked as ultrasound agents for both diagnosis and targeting therapeutic agents. These are designed in order to obtain efficient drug delivery. Micro and nanobubbles are very much used for targeting drug and achieving site specific release. These are stable and have longer residence time in systemic circulation, finally shows efficient and promising drug delivery [1]. These echogenic bubbles are helpful for disease diagnosis and therapy more prominently when compared with other novel drug delivery systems. This review describes about functioning of micro and nanobubbles along with mechanism, preparation and studies which describes the works on micro and nanobubbles.
