Swimming bacteria in 3D structured environments

Biological active matter is typically a rather heterogeneous collection of self-propelled microscopic objects displaying complex interactions among themselves and with the surrounding environment. Using advanced tools for 3D laser microfabrication and micromanipulation we can set up controllable and reproducible experimental conditions that allow to study complex phenomena with direct and quantitative methods. I will review our recent work in that direction including: 3D deterministic bacterial motors, bacterial motility in tight 1D confinement and a full 3D dynamical study of the wall entrapment phenomenon in swimming bacteria.
