Executive Industry Relevance

Atomic force microscopy (AFM)-based micro-indentation on human articular cartilage explants enables precise biomechanical profiling critical for early osteoarthritis research. Addressing practical artifacts in AFM workflows enhances predictive confidence in mechanical property measurements, supporting robust target validation and mechanistic de-risking at the discovery stage. This capability strengthens translational continuity from discovery through preclinical evaluation of disease-modifying interventions.
