title: Microbial cells analysis by atomic force microscopy.
abstract: Unraveling the structure of microbial cells is a major challenge in current microbiology and offers exciting prospects in biomedicine. Atomic force microscopy (AFM) appears as a powerful method to image the surface ultrastructure of live cells under physiological conditions and allows real-time imaging to follow dynamic processes such as cell growth, and division and effects of drugs and chemicals. The following chapter introduces different methods of sample preparation to gain insights into the microbial cell organization. Successful strategies to immobilize microorganisms, including physical entrapment and chemical attachment, are described. This step is a key step and a prerequisite of any analysis and persists as an important limitation to the application of AFM to microbiology due to the wide diversity of microorganisms. Finally, some applications are depicted which underlie the ability of AFM to explore living microbes with unprecedented resolution.
