The Onset of Microbubble Vibration

Ultrasound in Medicine & Biology, 2007
A linear relationship between the relative expansion of an off-resonance ultrasound contrast microbubble and low acoustic pressures is expected. In this study, high-speed optical recordings of individual phospholipid-coated microbubbles were used to investigate this relationship for microbubbles ranging from 2 to 11 microm and for acoustic pressures ...

Microbubbles Reforming Endothelium

AIP Conference Proceedings, 2006
Ultrasound contrast microbubbles have the ability to enhance cell permeability and thus may be used as a new way to deliver drugs inter-vascular. It facilitates the transfer of extracellular molecules into cells through ultrasound-activated microbubbles.

Microbubble intensification of bioprocessing

2020
Microbubbles 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 ...

Interaction of Microbubbles with Ultrasound

Echocardiography, 1999
The clinical need for bedside myocardial perfusion studies is obvious in the present era of revascularization. Animal and first clinical studies suggest that microbubbles can be used as intravascular tracers of perfusion in conjunction with echocardiography as an imaging modality.

Therapeutic Applications of Microbubbles

European Journal of Radiology, 2002
Microbubbles, 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 ...

Microbubbles for Medical Applications

2014
Ultrasound 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 ...

The lung as a filter for microbubbles

Journal of Applied Physiology, 1979
A 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 ...
