(A) Antibacterial activity of porous and non-porous electrospun PCL microfiber and nanofiber scaffolds without and with CAM on E. coli and (B) biofilm formation and antibiofilm activity. Regarding exact formulations, reference is made to Figure 1. Key: biofilm bacteria–biofilm bacteria washed off from the fiber scaffold; CAM—chloramphenicol; MF = microfiber; NF = nanofiber; planktonic bacteria–bacteria from the well where the fiber scaffold was removed. Detection limit refers to the CFU that can be counted by the plate method (200 CFU/mL).
