“…In contrast, there are concerns about cell damage, not only for the delivered cells but also for the inner wall of blood vessels near the target site, due to cavitation that occurs upon the destruction of bubbles under ultrasound exposure. [26][27][28][29][30][31][32][33] Since continuous irradiation of ultrasound is required to produce an effective force to propel BSCs, the effects on sound pressure and exposure time have been investigated. [34][35][36][37][38] In some studies, related to low-intensity pulsed ultrasound, 39,40) which investigated biological effects on cells, the parameters of ultrasound irradiation to proliferate endothelial cells 41,42) or to regress cancer cells 43) were discussed.…”

We investigated the viability of vascular endothelial cells engrafted on basement to verify protective effect from cell damage under ultrasound exposure with a frequency of 3 MHz and a maximum sound pressure of 400 kPa-pp. We used two types of lipid bubbles (LBs), which are LBs (+) to attach to the cells and LBs (–) not to attach to the cells. We confirmed that the engrafted cells on the basement stayed by ultrasound exposure and against flow resistance. We found a significant cell damage using LBs (–) regardless the flow condition, whereas cell damage was not observed with LBs (+). The difference in irradiation direction of ultrasound was not detected. By making use of the adhesion of LBs (+) on the cells, since there was a significant increase of the cell survival rate, we proved that a potential the adhesion of LBs (+) protected the cells from cell damage.

“…They presented the dynamics of the bubble's growth and demonstrated that its collapse process is influenced by thermodynamic effects. Huang et al [22] investigated the acoustic waves induced by the oscillation and collapse of a single cavitation bubble. They found that rarefaction waves are generated during the bubble collapse stage due to the contraction of the single bubble.…”

In this work, we performed molecular dynamics simulations to study the dynamics of a shock wave-induced single nanobubble collapsing near one flexible and two rigid boundaries. The flexible boundary consisted of polyethylene, and the rigid boundaries were made of aluminum and iron. The shock waves impinging on the nanobubble inside a molecular system were generated using a momentum mirror approach. For two relative wall distances, we studied the dynamics of the shock-induced single nanobubble and its collapse near the flexible and the rigid boundaries. The atomic velocity contours surrounding the single nanobubble and the collapse-induced damage on the boundaries were analyzed. We obtained this collapse-induced damage from ten collapsing nanobubbles. Results showed that the relative wall distance affected the single nanobubble’s collapse dynamics near the boundaries. A generated nanojet was directed on the surfaces during the collapse process. From the collapse-induced damage point of view, the depth damage of the polyethylene, iron, and aluminum boundaries for the relative wall distance of γ = 1.3 were 6.0, 0.47 and 0.63 nm, respectively. It was observed that the extensive collapse-induced damage occurred only on the polyethylene boundary.

Sonochemistry is a fascinating field that has drawn considerable interest from researchers across different disciplines. One of the key challenges in this field is the accurate characterization of the sonochemical field, which is crucial for understanding the underlying mechanisms and optimizing the process. To address this challenge, researchers have developed various monitoring methods that allow them to measure key parameters such as the intensity, frequency, and distribution of acoustic waves in the sonoreactor. In this review, we focus on the chemical dosimetry techniques that are commonly used for sonochemical monitoring. These techniques have been extensively studied in the literature and are known for their reliability and accuracy. However, as we will see, the performance of these techniques can vary depending on the chemical nature of the probing species and the experimental conditions, highlighting the need for a careful selection and calibration of the monitoring method. We begin by discussing the principles of chemical dosimetry in sonochemistry and how these methods can be used to measure key sono‐acoustic parameters. We then provide a detailed analysis of the various dosimetry techniques, including their advantages, limitations, and applicability under different operating conditions. In summary, our review serves as a valuable resource for researchers seeking to optimize their sonochemical experiments and contribute to the advancement of this fascinating field.
