Shows antibiotic perfusion through various biofilm models developed on black polycarbonate membranes as described in the methods. Panels a, d and A, D above represent the controls without any biofilm on the polycarbonate membranes, showing clear zones of inhibition of bacterial culture tested against gentamicin, cloxacillin,vancomycin and ciprofloxacin respectively. Panels b, c, e, f and B, C, E, F represent models in which biofilms were developed on the membranes. Whereas panels b, e and E show clear zones of inhibition of bacteria surrounding the biofilm, other panels like c, f, B, C and F show either no zone or very minimal zone. Antibiotics tested on each model have been named below the individual panels
