CPFX-incorporated and blank waterborne polyurethane films following co-culture with P. mirabilis in artificial urine. Following staining with propidium iodide/cyto9, CPFX films and control films were examined by confocal microscopy (magnification, ×200; scale bar, 100 µm). Viable bacteria were stained green, while non-viable bacteria presented with a red stain. (A) CPFX film (upper panel) and control film (lower panel) cultured with P. mirabilis for 2 days. (B) CPFX film (upper panel) and control film (lower panel) cultured with P. mirabilis for 7 days. CPFX, ciprofloxacin.
