In article number 1702982, Carlos Escobedo and co‐workers reveal that magnetotaxis enables directed motion of magnetotactic bacteria (MTB) in flows relevant to aquatic environments and biomedical applications. The ability of MTB to overcome a current is influenced by the magnetic field, the flow velocity, and their relative orientation. Magnetotaxis allows simultaneous guidance of multiple MTB along...
Magnetotactic bacteria (MTB) play an important role in Earth's biogeochemical cycles by transporting minerals in aquatic ecosystems, and have shown promise for controlled transport of microscale objects in flow conditions. However, how MTB traverse complex flow environments is not clear. Here, using microfluidics and high‐speed imaging, it is revealed that magnetotaxis enables directed motion of Magnetospirillum magneticum...
One of the important pursuits in science and engineering research today is to develop low-cost and user-friendly technologies to improve the health of people. Over the past decade, research efforts in microfluidics have been made to develop methods that can facilitate low-cost diagnosis of infectious diseases, especially in resource-poor settings. Here, we provide an overview of the recent advances...
We present a new on-chip pumping approach for microfluidic hanging-drop networks that are used for experiments with 3D microtissue spheroids. The pump includes a pneumatic chamber located directly above one of the hanging drops and uses the liquid-air-interface for flow-control. With this approach several independent hanging drop networks (HDN) can be operated in parallel with only one single pneumatic...
