Figure 6.
AFM height images of A. baumannii loose EPS (bright futures in the images pointed by arrows) immobilized on predefined areas of the silicon wafer surface before (a) and after (b) exposure to 10 mM maltodextrin. Both images were taken in liquid using the contact mode. The EPS swell after exposure to chemical stress, confirming the conformational changes of biopolymers on the substrate surface.
