Effect of Surface Chemistry and Young's Modulus on the Surface Motility of the Bacterium Pseudomonas Aeruginosa
… the effect of reducing the near-surface Young's modulus of the PDMS from 7000 to 70 kPA is investigated. For the lower modulus material, there is an increase in the likelihood of a bacterium executing sudden, high angle turns. This is evident in images with a framerate of one frame per …
