Fig. 7
The FE-SEM images showed the differences in E·faecalis morphology and biofilms among (A, D) biofilms treated with PBS (A ×5000; D ×20,000); (B, E) biofilms treated with 0.5 µg/mL CPC only (B ×5000; E ×20,000); (C, F) biofilms treated with 80 µg/mL AgNO3 only (C ×5000; F ×20,000); (G, J) biofilms treated with 2% CHX only (G ×5000; J ×20,000); (H, K) biofilms treated with 0.25 µg/mL CPC + 80 µg/mL AgNO3 (H ×5000; K ×20,000); (I, L) biofilms treated with 0.5 µg/mL CPC + 40 µg/mL AgNO3 (I ×5000; L ×20,000); (M, N, O) biofilms treated with 0.5 µg/mL CPC + 80 µg/mL AgNO3 (M ×5000; N ×20,000; O ×50,000)
