Infusion with gold nanoparticles had no significant effect on mechanical strength or integrity of PPDO sutures. The mechanical strength of the untreated and AuNP-infused PPDO sutures was tested by (A) the load-at-break method, (B) evaluating heat flux at various temperatures, and (C) melting temperature (T m ) of each sample by differential scanning calorimetry. No significant differences were noted on any of these parameters. The load-at-break values did not differ significantly between the two groups (Kruskal−Wallis one-way ANOVA on ranks, p < 0.05). The heat reflux curves superimposed on each other, and all measured T m values were around 112 °C.
