Artificial mini-heart

, 2017
Here we report the fabrication of an internal micropump based on magnetically actuated artificial cilia (MAAC) that functions like an artificial mini-heart. The micropump can provide versatile flows in a microfluidic channel network, when the MAAC are actuated to perform a tilted conical movement.

Implications of Tobacco Use on Pathogen‐Driven Diseases: A Public Health and Policy Perspective

World Medical &Health Policy, EarlyView.
ABSTRACT The tobacco epidemic remains one of the most significant global public health challenges, responsible for over 8 million deaths annually, with a substantial portion occurring among non‐smokers exposed to second‐hand smoke. While cigarette smoking remains the most prevalent form of tobacco use worldwide, the rise of electronic nicotine delivery

Development of an inhalable contrast agent targeting the respiratory tract mucus layer for pulmonary ultrasonic imaging

Scientific Reports
Impaired mucociliary transport is a distinguishing sign of cystic fibrosis, but current methods of evaluation are invasive or expose young patients to ionizing radiation. Contrast-enhanced ultrasound imaging may provide a feasible alternative.

A scanning particle image velocimetry system for spatial mapping of steady flow and O2 concentration fields around aquatic organisms

Methods in Ecology and Evolution, EarlyView.
Abstract The impact of flow on aquatic organisms (and vice versa) is crucial for many aspects of their physiology and ecology, as this interaction shapes the hydrodynamic boundary layer and thereby the exchange of solutes between the organism and its surrounding environment.

In vitro living system for streaming flow rectification

Physical Review Research
Small—but finite—fluid inertia can be leveraged to generate steady flows out of liquid vibrations around an immersed interface. In engineering, external high-frequency drivers (10^{2}–10^{5}Hz) allow this inertial rectification phenomenon, known as ...
