Melt Electrowriting of Amphiphilic Physically Crosslinked Segmented Copolymers [PDF]
Macromolecular Chemistry and Physics, 2021 AbstractVarious (AB)n and (ABAC)n segmented copolymers with hydrophilic and hydrophobic segments are processed via melt electrowriting (MEW). Two different (AB)n segmented copolymers composed of bisurea segments and hydrophobic poly(dimethyl siloxane) (PDMS) or hydrophilic poly(propylene oxide)‐poly(ethylene oxide)‐poly(propylene oxide) (PPO‐PEG‐PPO ...

Mimicking the Osteosarcoma Bone Microenvironment Using MEW-Printed PCL Scaffolds. [PDF]
Macromol BiosciPCL scaffolds exhibiting different MEW‐derived microarchitectures were coated either through physiological cell‐mediated mineralization or via direct calcium phosphate cement (CPC) deposition. Their mechanical characteristics, together with the behavior of SaOS‐2 osteosarcoma cells cultured on the scaffolds, were investigated to determine their ...
