Executive Industry Relevance

Capillary force lithography enables scalable fabrication of biomimetic substrata that replicate nanoscale extracellular matrix cues critical for cardiac tissue maturation. This approach supports predictive modeling of cardiomyocyte structure-function relationships, reducing reliance on empirical screening in early discovery. By providing reproducible, alignment-inducing platforms, the method enhances target validation confidence and translational continuity in cardiovascular R&D pipelines.
