What are microfluidic channels?
Microfluidic channels are small pathways used to manipulate fluids at a microscale, allowing for precise control in experiments.
How do marine microbes forage?
Marine microbes forage by sensing and moving towards nutrient gradients in their environment, a behavior known as chemotaxis.
What is shear flow?
Shear flow refers to the flow of fluid in which layers move parallel to each other at different speeds, affecting the movement of microorganisms.
Why is studying bacterial swimming behavior important?
Understanding bacterial swimming behavior is crucial for insights into their ecological roles and interactions in various environments.
What techniques are used to visualize microbial behavior?
Techniques such as video analysis and microscopy are commonly used to visualize and analyze microbial behavior in experiments.
