Fig. 2From: Investigations of biofilms formed on silica in contact with aqueous formulations containing laccase and maltodextrinAFM topography images obtained after contacting SiO2/Si substrates with laccase mixture suspension. Contact time of (a) 1 min, (b) 10 min, (c) 1 h, and (d) 4 h, showing regions of 2.5 µm x 2.5 µm width and exhibiting an extended height scale. Before imaging, substrates were rinsed with deionized waterBack to article page
