Ultrasound frequency-controlled microbubble dynamics in brain vessels regulate the enrichment of inflammatory pathways in the blood-brain barrier

Nature Communications
Microbubble-enhanced ultrasound provides a noninvasive physical method to locally overcome major obstacles to the accumulation of blood-borne therapeutics in the brain, posed by the blood-brain barrier (BBB).

Bubbles Acting as Micro End‐Effectors for Dexterous Manipulation and Sensing in Aqueous Environment

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Inspired by bubbles, this article proposes a low‐cost method for multifunctional manipulation and sensing using microbubbles in aqueous environments. Bubbles are easily generated in situ, enabling the safe and adaptive handling of microobjects and sensing of microforces and surface textures.

Comparison of Laser Doppler Flowmetry With Contrast-Enhanced Ultrasound to Approximate Placental Microvascular Blood Flow in the African Green Monkey (Chlorocebus aethiops sabaeus). [PDF]

J Med Primatol
ABSTRACT Background The ability to study in vivo microvascular flow within the placenta is limited. We sought to compare two techniques for evaluation of placental perfusion in a translational nonhuman primate model. Methods We measured placental microvascular perfusion in six pregnant African green monkeys (Chlorocebus aethiops sabaeus) using both ...

Design of a Reconfigurable Microfluidic System Enabled by Magnetic Miniature Robots

Advanced Intelligent Systems, EarlyView.
Magnetic miniature robots are integrated into microfluidic chips to achieve real‐time reconfiguration. By external magnetic actuation, the robots perform sorting, mixing, flow regulation, and bubble removal on demand. This versatile platform eliminates the need for complex on‐chip hardware and enables adaptive control for biological and chemical ...

Stability and Behavior of Bulk Nanobubbles Under Reservoir Conditions

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Compared with microbubbles, nanobubbles exhibit superior stability, higher specific surface area, and smaller size. These characteristics have increasingly attracted the attention of petroleum researchers. However, existing literature lacks studies on nanobubble concentration and size under harsh reservoir conditions. To address this gap, this
