Lipid-based microbubbles and ultrasound for therapeutic application.

Advanced Drug Delivery Reviews, 2020
Microbubbles with diagnostic ultrasound have had a long history of use in the medical field. In recent years, the therapeutic application of the combination of microbubbles and ultrasound, called sonoporation, has received increased attention as ...

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 ...

Mass transfer from freely rising microbubbles in aqueous solutions of surfactant or salt

, 2020
Microbubbles are used in many applications. One of the major advantages of using microbubbles is to improve the mass transfer of gases to the bulk phase.

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.

In situ characterisation of size distribution and rise velocity of microbubbles by high-speed photography

, 2020
Using microbubbles has gained significant interest in many domestic and industrial applications due to bubble stability in solution and increased mass transfer area.

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 ...
