Tiny 3D frog hydrogel scaffolds

Hydrogel frogResearchers in Austria have made these three-dimensional hydrogel scaffolds in the shape of tiny frogs. The frogs help demonstrate the efficacy of new water-soluble photoinitiators, developed by Robert Liska from Vienna University of Technology and colleagues, for fabricating micrometre-sized hydrogels quickly in complex, predesigned shapes.
