Radiopaque biodegradable polymeric composites for in vivo monitoring of TE products by X-rays imaging
Abstract
Introduction: Radiopaque properties enable in vivo monitoring of implants and occurring changes in their morphology, detect cracks and defects, etc.1 Improvement of radiodensity of polyesters can be improved by use of contrast agents.2,3 The aim of the study was to investigate the influence of widely used contrast agents, barium sulfate and iohexol, on degradation process of polyesters.Methods: Materials used in following experiments were prepared by solvent casting technique, dried in air at room temperature and then in a vacuum dryer. Materials were processed by Fused Deposition Modelling (FDM) method. Characterisation of composites were performed before and after incubation in phosphate-buffered saline (PBS). Thermal analysis, microscopic observations and calculation of mass loss and water absorption were investigated to characterise materials during degradation. Micro computed tomography and cytotoxicity assay of materials were also performed.Results: The obtained composites had much higher radiopacity than pure polymer. The addition of contrast agents did not cause considerable changes in properties of polyesters. There was no cytotoxic effect observed after the usage of contrast agents in contact with murine fibroblast cell line L929.Summary: The proposed contrast agents can be successfully used in non-invasive approach for in vivo monitoring of implanted TE products and correlation these data with tissue regeneration processes.
