Executive Industry Relevance

Polarization-sensitive two-photon microscopy (ps-2PFM) enables label-free, high-resolution structural characterization of amyloid aggregates, a critical challenge in neurodegenerative disease research. By resolving three-dimensional fibril organization within spherulites, this method enhances predictive confidence in early discovery and target validation workflows. Its ability to interrogate molecular ordering in complex biological systems supports risk-adjusted portfolio decisions for biopharma R&D.
