Daniel McKinnon publishes "Biophysically Defined and Cytocompatible Covalently Adaptable Networks as Viscoelastic 3D Cell Culture Systems" in Advanced Materials. He developed a cytocompatible covalently adaptable hydrogel that enabled cell spreading and fusion and will allow future studies on the role of matrix biophysical properties on cell function. Furthermore, the material can be used to quantitatively calculate the force a cell exerts on its surrounding, the energy expended in doing so, and the power required through the process.
