Simultaneous Measurement of Single-Cell Mechanics and Cell-to-Materials Adhesion Using Fluidic Force Microscopy

Ma Luo et al.

Summary: A new approach using fluidic force microscopy was presented to simultaneously measure the adhesion and viscoelastic properties of cells. The study found that the adhesive force and adhesion energy were correlated for each cell, while the viscoelastic properties had little dependence on cell shape. This methodology provides insight into the biophysics of multiple cell types.

A modified Sneddon model for the contact between conical indenters and spherical samples

Rui Han et al.

Summary: The study focused on the characterization of mechanical properties of materials through indentation techniques. The development of a modified Sneddon model for indenting spherical samples and investigation of the effects of sample diameter and indenter angles on indentation tests using finite element method (FEM) were conducted. The new model demonstrated reliable determination of the Young's modulus of spherical samples, filling the gap in contact mechanics and enriching experimental solid mechanics for the interpretation of indentation results.

Measurement of the interconnected turgor pressure and envelope elasticity of live bacterial cells

Huanxin Zhang et al.

Summary: This study established a nanoindentation method to measure the turgor pressure and envelope elasticity of live bacteria, and found that the Young's modulus of bacterial envelope is sensitive to the external osmotic environment, and turgor pressure is significantly dependent on the external osmotic stress. This method can not only quantify these mechanical properties of bacteria, but also help understand their behaviors in different environments.
