Abstract
Exposure to altered gravity influences cellular behaviour in cell cultures. Hydrogels are widely used tissue-engineering scaffolds and their mechanical properties are crucial for cell–matrix interactions, yet the impact of altered gravity on hydrogel properties remains unclear. Here we study the mechanical properties of PEGDA and PEGDA incorporated with graphene oxide (GO) by performing tensile tests in microgravity and hypergravity during a parabolic flight campaign, and by comparing them to tests performed at Earth gravity. We show that gravity levels do not result in a statistically significant difference in Young's modulus.
