3-D scaffolds. (A) Pores in the PLGA scaffold generated using the gas foaming method; (B) Pores in the PLGA scaffold generated using solvent casting and particulate leaching method; (C) Schematic of electrospinning of desired polymer solution and deposition of solid fibers on the target collector. The liquid polymer transforms into solid fibers because of the effect of high voltage [73,74].
