Executive Industry Relevance

Atomic force microscopy (AFM) cantilever-based nanoindentation enables quantitative measurement of nanoscale mechanical properties in both air and physiological fluids, supporting high-resolution biophysical characterization. This capability is critical for de-risking early discovery hypotheses, especially when distinguishing healthy from diseased cellular or tissue states based on mechanical phenotypes. The method's precision and adaptability across diverse sample types position it as a reusable platform for predictive confidence in biopharma R&D pipelines.
