Assessed by the micromanipulation technique, the main mechanical prope
rties of blood cells (red cell and white cell) are reviewed. Hyperelas
ticity of red blood cell membrane is characterized and corresponding m
aterial 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 o
f two elastic cell in contact when adhesion is taken into account is s
pecified.
