Wande Zhang, Pranav Soman, Kyle Meggs, Xin Qu and Shaochen Chen Tuning the Poisson's Ratio of Biomaterials for Investigating Cellular Response Advanced Functional Materials 23
A methodology to develop suspended structures with tunable Poisson's ratios is reported. Two-photon polymerization is used to fabricate suspended web structures with a negative Poisson's ratio (NPR), based on analytical models. This technique could be used to investigate effects of altering the Poisson's ratio of several photocurable biomaterials on a variety of cellular aspects including morphology, gene expression, and migration using different cell types.
