WebScaffolds for tissue engineering applications were fabricated from PGCL copolymer using the solvent-casting and particle-leaching technique. The PGCL scaffolds produced in this fashion had open pore structures (average pore size = 250 μm) without the usual nonporous skin layer on external surfaces. WebJan 1, 2007 · In this study, PCL scaffolds incorporating hydroxyapatite (HAp) particles were fabricated by com- bined solvent casting and particulate leaching techniques. The average pore dimension was in the range of about 480-500 lm. The porosity, water absorption, and compres- sive modulus of the scaffold were evaluated.
