Shrinking microbubbles with microfluidics: mathematical modelling to control microbubble sizes [PDF]
Soft Matter, 2017 Microbubbles have applications in industry and life-sciences. In medicine, small encapsulated bubbles (< 10 μm) are desirable because of their utility in drug/oxygen delivery, sonoporation, and ultrasound diagnostics. While there are various techniques for generating microbubbles, microfluidic methods are distinguished due to their precise control ...

Effect of Surface‐Lubricant Compatibility on Bubble Formation in Lubricant‐Infused Surfaces
Advanced Materials Interfaces, EarlyView.Lubricant‐infused surfaces reduce drag partly through bubbles that form when lubricant depletes. Using laser‐textured steel infused with silicone oil, we show that microbubble nucleation occurs even on surfaces fully wetted by the lubricant, regardless of chemistry.

Multiscale Acoustic Bubble Actuators Using Bioinspired Liquid‐Repellent Microstructures
Advanced Materials Technologies, EarlyView.The article presents multiscale acoustic bubble actuators using bioinspired liquid‐repellent microstructures, enabling programmable trapping, pumping, mixing, and precise flow control. Mimicking springtail microstructures, these scalable actuators (200 µm–1 mm) offer multifunctionality in all‐in‐one devices, letter‐shaped arrays, and 3D cube ...

Complementary correlation between surface microbubble and droplet shapes
AIP AdvancesPrevious atomic force microscopy studies have suggested that surface micro- and nanobubbles exhibit a flat shape. In this study, we directly observed surface microbubbles formed in an NH3BH3 solution using an optical microscope. No flat microbubbles were

Magnetic resonance imaging of oxygen microbubbles
Healthcare Technology Letters, 2019 Oxygen loaded microbubbles are being investigated as a means of reducing tumour hypoxia in order to improve response to cancer therapy. To optimise this approach, it is desirable to be able to measure changes in tissue oxygenation in real-time during ...

Cross‐Scale Hierarchical Targeted Delivery System Based on Small‐Scale Magnetic Robots
Advanced Robotics Research, EarlyView.This article reviews a cross‐scale hierarchical targeted delivery system that integrates magnetic continuum robots and magnetic microrobots. By combining rapid long‐range navigation with precise microscale targeting, the system overcomes key limitations of single‐scale approaches.
