Application of the two-step sterilization approach for the decontamination of biomaterials with nano-patterned surfaces. A) surface of silica wafer coated with PCL nano-fibers; B & F) S. aureus contaminated surfaces; C & G) S. aureus contaminated surfaces treated with discharge argon generated at low power (60 watts) for 8 min; D & H) S. aureus contaminated surfaces treated with discharge argon generated at high power (100 watts) for 6 min; E) the same S. aureus contaminated surfaces treated with the conventional autoclaving method. Nano-structures on the surface were completely destroyed. A-E are SEM images. F-G are confocal microscopy images acquired using Live/Dead kit.
