Abstract
Optical trapping with structured optical fibers is reported for five species of the Pseudomonas genus. Contactless trapping at low intensities was realized with 3D printed Fresnel lens fibers and an original fiber emitting a tightly focused annular beam. Specific swimming features and the behavior of trapped bacteria of the investigated species are compared applying different numerical methods.
