The Study of Mechanical Properties of Biological Cells

Cells are the basic unit of all living organisms. They can realize various specific functions of living organisms such as energy conversion, material transportation, signal transduction, and expression of genetic information. They are the foundation for human research on the life activities of all living organisms. As a line of defense for cells to protect themselves, the cell membrane has certain mechanical properties that can ensure the balance and stability of various normal biochemical reactions inside and outside the cell during its survival, such as cell growth, movement, division, etc. When cells face changes in the environment, their surface mechanical properties will also change to a certain extent. However, the mechanism and manner in which cells respond to environmental influences are still not very clear. Therefore, in order to understand this complex mechanical behavior of cells in living organisms, it is necessary to analyze the mechanical properties of the cell surface.
