Imaging of bacteria by AFM

Fast screening of bacteria would allow testing pharmaceuticals in an automated manner (Braga & Ricci, 1998).  Bacteria were prepared using different approaches for fixation, but mainly for good imaging conditions. To achieve high resolution on bacteria, adsorption has been an extended issue and using poly-L-lysine even from different manufacturers changes adsorption (Doktycz et al., 2003).  Dried bacteria however were imagable.
