Atomic force microscopy (AFM) has recently provided the great progress in the study of micro- and nanostructures including living cells and cell organelles. Modern AFM techniques allow solving a number of problems of cell biomechanics due to simultaneous evaluation of the local mechanical properties and the topography of the living cells at a high spatial(More)
The changes in passive ion permeability of the red blood cell membrane after peroxynitrite action (3 microM-3 mM) have been studied by biophysical (using radioisotopes of rubidium, sodium and sulphur (sulphate)) and electrophysiological methods. The enhancement of passive membrane permeability to cations (potassium and sodium ions) and the inhibition of(More)
Atomic force microscopy (AFM) was used to study surface layers of fixed intact erythrocytes. Advantages of simultaneous analysis of surface topography and lateral force maps in the investigation of cytoskeleton structure were shown. Fractal analysis was applied to the lateral force maps of erythrocyte surfaces to evaluate the complexity of the cytoskeleton.(More)
