Fig. 3. Psl immobilizes and delays C. elegans from escape and attacking susceptible biofilms.

a Schematic representation of trapping C. elegans by biofilms under blue light repulsion. b Duration taken by C. elegans to escape biofilm trap. c Schematic representation of trapping and baiting C. elegans. d Extent of roaming of C. elegans on bait biofilm after leaving the trap biofilm. Means and SD from triplicate experiments are shown. **P < 0.01, ***P < 0.001, ns not significant, one-way ANOVA.
