EPISODE 3: The Hidden Mechanical Properties of Biological Surfaces – Brillouin Endo-Microscopy

In this episode, we uncover a revolutionary approach to imaging the hidden mechanical properties of biological surfaces using Label-Free Brillouin Endo-Microscopy. Unlike traditional imaging techniques that rely on fluorescent labels, this method provides quantitative 3D viscoelastic mapping at the sub-micrometre scale—offering unprecedented insights into biological structures.

🔍 Key Topics Covered:

• How Brillouin scattering enables real-time mechanical imaging of living tissue

• First-ever 3D stiffness mapping of Caenorhabditis elegans cuticle in situ

• Potential applications for non-invasive diagnostics and disease research

• The future of elasticity-based biomedical imaging

📖 Based on the research article:
