You should summarize the working principle of the micromechanical tool with a brief explanation of the

mechanical model used in the system. For example, how exactly the cellular force is measured and

calculated using PDMS micropillars? The review can be written on one page (if necessary could be

expanded to two pages) with figures and references

AFM, traction force microscopy

PDMS micropillar array

Optical tweezers

Ultrasound tweezers
