Advance in Bacteria Chemotaxis on Microfluidic Devices

In comparison with traditional chemotaxis detection methods, microfluidic assay has an accurate control over bacterial microenvironment with higher sensitivity. In this paper, the microfluidic chemotaxis detectors that appeared in recent years were introduced from the aspect of chip structure, working principle and their applications. Finally, we provided insights into the challenges of bacterial chemotaxis and provided future perspectives.
