  • Porogen leaching is one of the most common methods used for preparation of scaffolds with controlled porosity. The particulate leaching method is totally based upon the dispersion of porogen (salt, sugar and wax) either in liquid particulates or powdered materials (Hou et al., 2003; Lee et al., 2004, Nazarov et al., 2004 Vepari & Kaplan, 2007) by the process of evaporation, cross linking or other reaction liquid may be solidified. These porogens act as place holder for pore and interconnection of the pores in the actual scaffolds fabrication technique.

  • An appropriate liquid-liquid phase separation is critical for the preparation of nanofibers and does not occur in all solvents that’s why selection of solvent and phase separation temperature is crucial for the formation of nanofibers. When the condition are favourable, liquid-liquid phase separation produce three dimensional fibrous structure with nano scaled architecture similar to that of collagen type I, and used in various biomedical applications.

  • Particulate leaching is one of the popular techniques that are widely used to fabricate scaffolds for tissue engineering applications (Ma & Langer, 1999; Lu et al, 2000). Salt, wax or sugars known as porogens are used to create the pores or channels. Here salt is grounded into small particles and those particles that have desired size are poured into a mold and filled with the porogen. A polymer solution is then cast into the salt-filled mold. After the evaporation of the solvent, the salt crystals are leached away using water to form the pores of the scaffold. The process...
