Optical Whispering-Gallery-Mode Microbubble Sensors

Micromachines, 2022
Whispering-gallery-mode (WGM) microbubble resonators are ideal optical sensors due to their high quality factor, small mode volume, high optical energy density, and geometry/design/structure (i.e., hollow microfluidic channels).

Focal areas of increased lipid concentration on the coating of microbubbles during short tone-burst ultrasound insonification. [PDF]

PLoS ONE, 2017
Acoustic behavior of lipid-coated microbubbles has been widely studied, which has led to several numerical microbubble dynamics models that incorporate lipid coating behavior, such as buckling and rupture.

Microbubbles in Food Technology

Annual Review of Food Science and Technology, 2023
Microbubbles are largely unused in the food industry yet have promising capabilities as environmentally friendly cleaning and supporting agents within products and production lines due to their unique physical behaviors. Their small diameters increase their dispersion throughout liquid materials, promote reactivity because of their high specific ...

Nonspherical ultrasound microbubbles

Proceedings of the National Academy of Sciences, 2023
Surface tension provides microbubbles (MB) with a perfect spherical shape. Here, we demonstrate that MB can be engineered to be nonspherical, endowing them with unique features for biomedical applications. Anisotropic MB were generated via one-dimensionally stretching spherical poly(butyl cyanoacrylate) MB above their glass transition temperature ...

Microbubble cavitation imaging [PDF]

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2013
Ultrasound cavitation of microbubble contrast agents has a potential for therapeutic applications such as sonothrombolysis (STL) in acute ischemic stroke. For safety, efficacy, and reproducibility of treatment, it is critical to evaluate the cavitation state (moderate oscillations, stable cavitation, and inertial cavitation) and activity level in and ...

Sonothrombolysis with BR38 Microbubbles Improves Microvascular Patency in a Rat Model of Stroke. [PDF]

PLoS ONE, 2016
Early recanalization of large cerebral vessels in ischemic stroke is associated with improved clinical outcome, however persisting hypoperfusion leads to poor clinical recovery despite large vessel recanalization.

Polymer Mechanochemistry in Microbubbles

Advanced Materials, 2023
AbstractPolymer mechanochemistry is a promising technology to convert mechanical energy into chemical functionality by breaking covalent and supramolecular bonds site‐selectively. Yet, the mechanochemical reaction rates of covalent bonds in typically used ultrasonication setups lead to reasonable conversions only after comparably long sonication times.
