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.

Ultrasound, microbubbles, and thrombolysis

Progress in Cardiovascular Diseases, 2001
Although 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.

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 ...

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 ...

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 ...

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 ...

Radial modulation of single microbubbles

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2009
Radial modulation imaging is a new promising technique to improve contrast-enhanced ultrasound images. The method is based on dual-frequency insonation of contrast agent microbubbles. A low-frequency (LF) pulse is used to modulate the responses of the microbubbles to a high-frequency (HF) imaging pulse.
