Biomimicking the mechanical properties of native tissues is one key requirements engineering tissue scaffolds, rendering a need for materials and manufacturing processes with high level control over such scaffolds. To address this need, we present 3D printable, composite hydrogel consisting sodium alginate (SA), gelatin (GEL) gum Arabic (GA), referred to herein as SA-GEL-GA hydrogel, which can ...

Background & Aims: Chronic pulmonary infection in patients with cystic fibrosis is predominantly due to infection by mucoid strains of Pseudomonas aeruginosa. Mucoid P. aeruginosa is due to the production of exopolysaccharide called also alginate. Alginate in addition to interference with the clearance of lung has antiphagocytic property. Optimal killing activity of P. aeruginosa requires opson...
