Evaluation of Sterilisation Techniques for Regenerative Medicine Scaffolds Fabricated with Polyurethane Nonbiodegradable and Bioabsorbable Nanocomposite Materials

Figure 2

POSS-PCL and POSS-PCU FTIR spectra after different sterilisation techniques. [a] SDIC treatment led to a slight decrease in the peaks at 1634 cm⁻¹ and 1557 cm⁻¹ and an increase in the peak at 1520 cm⁻¹ compared to untreated control POSS-PCL. [b] No major changes were noted in the FTIR spectra of POSS-PCU samples after different sterilisation methods.
