Assessed by the micromanipulation technique, the main mechanical properties of blood cells (red cell and white cell) are reviewed. Hyperelasticity of red blood cell membrane is characterized and corresponding material coefficients are given. Surface tension and cell viscosity of leukocyte are discussed and related values are stated. Some aspects of cell contact mechanics are developed. The fundamentals of mechanics of two elastic cell in contact when adhesion is taken into account is specified.
