Development of exosome membrane materials-fused microbubbles for enhanced stability and efficient drug delivery of ultrasound contrast agent

open access: yesActa Pharmaceutica Sinica B, 2023
Lipid-coated microbubbles are widely used as an ultrasound contrast agent, as well as drug delivery carriers. However, the two main limitations in ultrasound diagnosis and drug delivery using microbubbles are the short half-life in the blood system, and ...

Laser-Controlled Propulsion of a Microbubble Rolling on a Carbon Nanocoil Rail [PDF]

open access: yesNanomaterials
Controllably propelling microbubbles in microchannels within a microfluidic chip is of great scientific significance yet remains challenging. In this work, we employ carbon nanocoils (CNCs) as a laser-energized rail for propelling microbubbles to the ...

The Impact of Lipid Handling and Phase Distribution on the Acoustic Behavior of Microbubbles

open access: yesPharmaceutics, 2021
Phospholipid-coated microbubbles are ultrasound contrast agents that can be employed for ultrasound molecular imaging and drug delivery. For safe and effective implementation, microbubbles must respond uniformly and predictably to ultrasound.

Microbubble surface modes [PDF]

open access: yesIEEE Ultrasonics Symposium, 2004, 2005
We have investigated surface vibrations generated by ultrasound excitation of individual unencapsulated micron-sized bubbles. In addition, we present surface modes (n=2 and 3) observed for phospholipid-coated ultrasound contrast agents excited through excitation of radial modes at frequencies between 1 and 4 MHz.

On the theory of multiple encapsulated microbubbles interaction: Effect of lipid shell thickness

open access: yesCase Studies in Thermal Engineering, 2023
Encapsulated microbubbles are empty, micrometer-sized, spherical bubbles, typically micron which are used in many applications as lipid-shells in soft tissues.

Microbubbles in Food Technology

open access: yesAnnual 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 ...

Microbubble cavitation imaging [PDF]

open access: yesIEEE 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 ...

Nonspherical ultrasound microbubbles

open access: yesProceedings 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 ...
