This paper compares volume and surface methods for microparticle traction force microscopy through simulations and experiments, finding the surface method more accurate but with reduced performance at high noise levels.

This paper introduces DNA-based hydrogel microparticles with tunable mechanical properties for 3D cellular systems, showing they can be remodeled by fibroblast spheroids based on their stiffness.

This paper introduces DNA microbeads to control morphogen release in organoids, enabling spatio-temporal regulation of development and improving tissue mimicry.
