Fig. 4From: Fabrication of three-dimensional hydrogel scaffolds for modeling shunt failure by tissue obstruction in hydrocephalusAlginate scaffold pore structure. Scanning electron microscopy image illustrating the pore structure of the alginate scaffolds. Sheets of alginate form cone-shaped pores. The narrowest diameters of these pores averaged 296.2 ± 83.8 µm (n = 5)Back to article page
