Atomic Force Microscopy

Atomic Force Microscopy

Atomic force microscopy (AFM) is a type of scanning probe microscopy that can analyze topographic details of various specimens like ceramics, glass, polymers, and biological samples. AFM offers over 1000 times more resolution than the optical imaging system. Images generated from AFM are three-dimensional surface profiles, offering an advantage over the flat, two-dimensional images from other imaging techniques.
The AFM Probe
The probe is regarded as the heart of any AFM setup and comprises the...

Background:

Cell-generated forces are crucial for biological processes like migration, division, and morphogenesis.
Traction Force Microscopy (TFM) quantifies cellular forces on substrates and internal tissue stresses.
Existing TFM techniques require established protocols for accurate force measurement.

Purpose of the Study:

To provide a comprehensive protocol for performing TFM on 2D micropatterned substrates.
To enable the calculation of internal mechanical stress within cells using Monolayer Stress Microscopy (MSM).
To offer optimized Python code for high-throughput batch analysis of TFM data.

Main Methods:

The protocol details sample preparation for 2D micropatterned polyacrylamide substrates.
It includes imaging of substrate deformations caused by cells.
TFM analysis uses custom Python code, and MSM analysis utilizes pyTFM software.

Main Results:

The protocol facilitates non-invasive, spatially and temporally resolved force and stress mapping.
It enables the generation of rich datasets for studying cell mechanics.
The methods are optimized for batch analysis, increasing throughput.

Conclusions:

This protocol provides a robust framework for TFM and MSM on 2D substrates.
The developed methods offer valuable tools for investigating cell-generated forces in health and disease.
The high-throughput analysis capabilities support extensive data generation for mechanobiology research.
