The surface area of brand new catheters with visible grooves (a) AFM image, scan area – 10 ×10 μm, colour scale 500 nm. (b) SEM image, horizontal side of the image – 8.3 μm
Fig. 2
An AFM image (a) and SEM images (b, c) of the catheter surface – Staphylococcus spp. covered with biofilm. The scales are shown in the pictures
Fig. 3
SEM images of the catheter: (a) formation of biofilm by connecting bacteria using exopolysaccharide skeleton (b) Staphylococcus spp. colonies covered with biofilm
