Ultrasound and microbubbles to beat barriers in tumors: improving delivery of nanomedicine.
Advanced Drug Delivery Reviews, 2021 Successful delivery of drugs and nanomedicine to tumors requires a functional vascular network, extravasation across the capillary wall, penetration through the extracellular matrix, and cellular uptake. Nanomedicine has many merits, but penetration deep

Microbubble surface modes [PDF]
IEEE 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
Case 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.

Current Opinion in Colloid & Interface Science, 2021 The field of medical ultrasound has undergone a significant evolution since the development of microbubbles as contrast agents. However, due to their size, microbubbles remain in the vasculature, and therefore have limited clinical applications. Building

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 ...
