3D Printed, PVA⁻PAA Hydrogel Loaded-Polycaprolactone Scaffold for the Delivery of Hydrophilic In-Situ Formed Sodium Indomethacin.

ABSTRACT: 3D printed polycaprolactone (PCL)-blended scaffolds have been designed, prepared, and evaluated in vitro in this study prior to the incorporation of a polyvinyl alcohol⁻polyacrylic acid (PVA⁻PAA) hydrogel for the delivery of in situ-formed sodium indomethacin. The prepared PCL⁻PVA⁻PAA scaffold is proposed as a potential structural support system for load-bearing tissue damage where inflammation is prevalent. Uniaxial strain testing of the PCL-blended scaffolds were undertaken to determine the scaffold’s resistance to strain in addition to its thermal, structural, and porosimetric properties. The viscoelastic properties of the incorporated PVA⁻PAA hydrogel has also been determined, as well as the drug release profile of the PCL⁻PVA⁻PAA scaffold. Results of these analyses noted the str
