3D Bioplotter Research Papers

Poly(ε-caprolactone) (PCL) chain cleavage results in the formation of polar terminal species, comprising hydroxy and carboxyl groups that enhance surface hydrophilicity and enable subsequent biofunctionalization. However, the direct effects of various acidic and basic treatments on 3D printed PCL scaffolds have not been studied from a functional perspective. In this study, we comprehensively assessed the influence of acid (hydrochloric, HCl) and base (sodium hydroxide, NaOH) catalyzed hydrolysis across different conditions on various properties of 3D printed PCL scaffolds. Analyses included testing of physiochemical and mechanical properties, and assessment of rate and stability of surface-nucleating bioactive apatite-like minerals. HCl exposure resulted…
