Researchers study the viscoelasticity of human cells as a response to external cues using the high-throughput AFS®

Measure Cell Mechanics with Acoustic Force Spectroscopy

A recent publication in Small introduces you to the value of acoustic force spectroscopy (AFS®) to study the viscoelastic properties of individual cells in high throughput. The authors describe how they used this “plug-and-play” instrument to measure mechanical cell properties upon external cues seamlessly.

Romanov et al. specifically assessed how alterations to three parameters (temperature, drug exposure, or membrane-protein expression) influence the viscoelastic characteristics of human cell line HEK293T. In essence, the team could distinguish between cell viscosities by assessing the so-called mean square displacement of randomly moving cells, which describes their deviation from a reference specific position.

Using this method, the researchers explored changes to the stiffness and fluidity of the cells upon changes in their immediate environment.

“The AFS presents as a powerful tool for capturing the heterogeneity of living cells through rapid, high-throughput measurements of cellular viscoelasticity,” the authors concluded. “A significant advantage of the technique is the ‘plug-and-play’ format that makes force calibration and viscoelastic measurements intuitive and easy.”
