Fabrication of porous scaffolds: advantages and disadvantages.

Method	Advantages	Disadvantages	References
Particulate Leaching	Modulate pore size and porosity	Limited pore shape and size	[15]
Solvent Casting	Modulate pore size and porosity Easy incorporation of drugs within the scaffold	Low pore interconnectivity	[100,101]
Emulsion Templating	Modulate particle size, high porosity, interconnectivity	Difficulty in obtaining emulsions with sufficient monodispersity for crystallization	[16,102,103]
Gas Foaming	Modulate pore size and porosity Free of toxic organic solvents	Unexpected pore interconnectivity	[104,105,106]
Melt Molding	Modulate pore size and porosity	High temperature required when molding	[107]
