Visible images of porogens and the pores within scaffolds. Gelatin particles generated by the microfluidic device with different diameters (a–c), NaCl particles (d), and porous scaffolds (e–h). Gelatin particles with diameter of (a), (b), (c), and NaCl particle with size of 250-350 μm (d). Scaffolds produced from inverse opal technique (e–g) and from salt leaching method (h).
