Modeling the synergistic enhancement of drug permeation by a dual-microbubble system under ultrasonic excitation [PDF]
The high selectivity of the vascular endothelium, exemplified by the blood–brain barrier (BBB), provides critical protection to tissues against harmful substances; however, it also severely restricts the targeted delivery of therapeutic agents ...

In vitro evaluation of PEI-coated microbubble– neutrophil conjugates for ultrasound-guided cell delivery [PDF]
BackgroundImmunotherapies have advanced cancer treatment; however, their clinical efficacy remains limited for solid tumors due to challenges associated with effectively directing immune cells into the complex tumor microenvironment.

Translational motions and radial oscillations of a polymer-coated microbubble in the focal cross-section of focused acoustic vortex [PDF]
The polymer-coated microbubble stimulated by focused acoustic vortex has great potential in enhancing the targeted drug delivery, but the dynamic behaviors of the microbubble in the focal cross-section of focused acoustic vortex requires further ...

Optical Whispering-Gallery-Mode Microbubble Sensors
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).

Optical microbubble resonator [PDF]
We develop a method for fabricating very small silica microbubbles having a micrometer-order wall thickness and demonstrate the first optical microbubble resonator. Our method is based on blowing a microbubble using stable radiative CO(2) laser heating rather than unstable convective heating in a flame or furnace.

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

CEUS LI-RADS: a pictorial review [PDF]
Contrast-enhanced ultrasound (CEUS) greatly improved the diagnostic accuracy of US in the detection and characterization of focal liver lesions (FLLs), and it is suggested and often included in many international guidelines as an important diagnostic ...

Mass transfer between microbubbles [PDF]
The role of interfacial coatings in gas transport dynamics in foam coarsening is often difficult to quantify. The complexity of foam coarsening measurements or gas transport measurements between bubbles requires assumptions about the liquid thin film thickness profile in order to explore the effects of interfacial coatings on gas transport.
