Bridging Scales: Unveiling the mechanical properties of biomaterials and organoids with AFM and Bulk Rheology

March 11–13, 2026 | i3S, Porto

Techniques capable of providing insight into the mechanical properties of biological samples, engineered tissues and organoids are key for developing advanced 3D models that closely replicate the characteristics of native tissues/organs. These techniques not only enhance the physiological relevance of in vitro models but also contribute to reducing the reliance on animal testing.

Specifically, this course will show how Atomic Force Microscopy (AFM) and Rheology can be used to characterize the viscoelastic properties of (bio)materials at the nano-and macroscale, respectively, including stiffness, adhesion, Young's modulus, viscous modulus, and viscosity, without prior sample preparation. Additionally, the course will present high-throughput nanoindentation integrated with imaging for advanced 3D model screening.

Participants will get acquainted with these techniques through lectures and hands-on sessions, while engaging with various data acquisition modes and software for data processing.

By the end of the course, participants will be able to:

  • Apply AFM for nanoindentation and dynamic mechanical analysis
  • Learning how to properly calibrate the AFM to ensure accurate and reliable force measurements
  • Understand core mechanical parameters (e.g., stiffness, Young’s modulus)
  • Select the appropriate models and software for data processing and analysis
  • Use rheological methods (oscillatory shear, viscometry)
  • Be acquainted with high-throughput nanoindentation integrated with imaging and with its potential for mechanical properties mapping.

Target audience: Postdoctoral researchers, PhD, MSc and BSc students; life sciences researchers, technical staff, members of technology centers and industry professionals.

Course duration: 21 hours (over 3 days)

Course Format: In person | Includes both theoretical and practical components

  • Fundamental concepts of AFM
  • Methodologies for calibrating cantilever sensitivity and spring constants
  • Analysis of systematic and random errors affecting force measurements in soft biological materials
  • Analysis of AFM Power Spectral Density and force-distance curves
  • Application of computational fitting models (e.g., Hertz, Sneddon) in AFM data analysis
  • Mechanical analysis of 3D biological samples (such as spheroids, organoids, and hydrogels using AFM)
  • Simultaneous mapping of nanomechanical properties and imaging of sample topography using the Quantitative ImagingTM (QITM) mode in AFM
  • Fundamental concepts of rheology
  • Bulk rheology and mesorheology of spheroids
  • Microrheology using Optical Tweezers and AFM as complementary tools to investigate viscoelastic properties of subcellular structures such as chromosomes
  • Oscillatory shear testing and interpretation of experimental data (frequency sweep analysis and model fitting)
  • Viscometry and flow curve characterization through shear rate vs. viscosity analysis
  • Mechanobiology: Understanding the role of mechanics in health and disease
  • Live equipment demonstration: High-Throughput nanoindentation integrated with imaging, applied to the characterization of 3D engineered constructs
