Atomic force microscopy of animal cells: Advances and prospects

We review the advances of the method of atomic force microscopy (AFM) for investigating the animal cells and analyze its development, paying much attention to studies of living cells. We consider the specific features and tasks of AFM, and a number of special AFM-based techniques. We discuss the choice of probe geometry for studies of animal cells, determination of cell adhesion on substrate, mapping of the cell surface using chemically modified cantilevers, and analysis of the distribution of molecular components inside the cell with the use of micro- and nanosurgical approaches, as well as combining AFM with optical and laser scanning confocal microscopy, and the possible applications of AFM in biotechnology and medicine.
