Therapeutic applications of microbubbles
European Journal of Radiology, 2002Microbubbles, currently used as contrast agents have potential therapeutic applications. Microbubbles, upon insonation of sufficiently intense ultrasound will cavitate. Cavitation with microbubbles can be used to dissolve blood clots or deliver drugs. Targeting ligands and drugs can be incorporated into microbubbles to make highly specific diagnostic ...

Microbubble intensification of bioprocessing
2020Microbubbles have been involved in industrial processing since the 1970s with the introduction of dissolved air flotation into common practice. The turn of the century saw microbubbles become regularly used in medical imaging. But in bioprocessing, only this decade has seen rapid advances in R&D, with some bioprocesses, particularly in wastewater ...

Microbubbles for Medical Applications
2014Ultrasound contrast agent (UCA) suspensions contain encapsulated microbubbles with radii ranging from 1 to 10 micrometers. The bubbles oscillate to the driving ultrasound pulse generating harmonics of the driving ultrasound frequency. This feature allows for the discrimination of non-linear bubble echoes from linear tissue echoes facilitating the ...

Ultrasound, microbubbles, and thrombolysis
Progress in Cardiovascular Diseases, 2001Although dissolution of thrombus using ultrasound has been attempted for over 25 years, the clinical use of this technique remains limited. The ability of microbubbles to potentiate ultrasound-induced thrombolysis has renewed interest in this technique, which recanalizes occluded vessels without the need for fibrinolytic therapy.

The lung as a filter for microbubbles
Journal of Applied Physiology, 1979A new ultrasonic Doppler device has been used noninvasively over the femoral artery of anesthetized dogs to prove that it can detect carefully calibrated microbubbles of 14--189 micrometers diam when these are infused directly into the aorta. The same evaluated technique has then been employed to detect any bubbles escaping into the arterial system ...

Multifunctional Ultrasound Microbubbles
Chemical ReviewsMicrobubbles (MBs) have served as ultrasound (US) contrast agents for over 30 years in cardiac imaging and liver tumor characterization. Moreover, in recent years, molecularly targeted MBs are currently under clinical evaluation for oncological and inflammatory diseases.
