3D auxetic metamaterials as scaffolds for cell growth (Conference Presentation)

Paper Abstract

We present our latest work into the modelling and laser fabrication of 3D auxetic metamaterials, and their evaluation as scaffolds for cell growth. Auxetic metamaterials are materials that display a negative Poisson’s ratio; when stretched, they become thicker perpendicular to the applied force. Their properties are due to their architecture, rather than their chemical composition. Natural biological tissues display auxetic characteristics in organs such as skin, artery, tendon, and cancellous bone. To make these metamaterials scaffolds, we employ 3D multiphoton polymerisation, using a biocompatible tailor-made zirconium silicate. Finally, we investigate the suitability of these metamaterials as scaffolds for cell growth.
