The ability to precisely control the properties of natural polymers and fabricate three-dimensional (3D) structures is critical for biomedical applications. In this work, we report printing complex 3D made soft polysaccharide (chitosan) inks directly in air at room temperature. We perform a comprehensive characterization process by analyzing effect ink (i.e., rheological solvent evaporation) process-related parameters nozzle diameter, robot velocity, applied pressure). effects neutralization...

Skeletal muscle displays a marked accumulation of denervated myofibers at advanced age, which coincides with an acceleration atrophy. In this study, we evaluated the hypothesis that in age is due to failed reinnervation by examining from young adult (YA) and very old (VO) rats murine model sporadic denervation secondary neurotrypsin over-expression (Sarco mouse). Both aging rat Sarco mouse exhibited fiber-type grouping, consistent repeating cycles reinnervation, yet VO muscle, rapsyn...

Bioelastomers are extensively used in biomedical applications due to their desirable mechanical strength, tunable properties, and chemical versatility; however, three-dimensional (3D) printing bioelastomers into microscale structures has proven elusive. Herein, a high throughput omnidirectional approach via coaxial extrusion is described that fabricates perfusable elastomeric microtubes of unprecedently small inner diameter (350-550 µm) wall thickness (40-60 µm). The versatility this shown...
