3D printing MOF nanozyme hydrogel with dual enzymatic activities and visualized glucose monitoring for diabetic wound healing

Chemical Engineering Journal 2023 Volume 471, Article 144649

Promoting rapid healing of diabetic wounds caused by hyperglycemia, bacterial infection, and chronic inflammation is a global challenge. To address this issue, we design and prepare a novel cerium-based MOF nanozyme hydrogel via 3D printing technology to provide a personalized hydrogel wound dressing. The hydrogel is unique in that cerium-based MOFs are grown into the hydrogel network, simplifying the printing process of MOF hydrogel. The prepared hydrogel exhibits specific catalytic activity to various oxygen free radicals and glucose concentration-dependent color changes due to the interconversion between different valence cerium ions. This feature allows for indirect monitoring of glucose content around…

Three-Dimensional Printing Fiber Reinforced Hydrogel Composites

ACS Applied Materials & Interfaces 2014 Volume 6, Issue 18, Pages 15998–16006

An additive manufacturing process that combines digital modeling and 3D printing was used to prepare fiber reinforced hydrogels in a single-step process. The composite materials were fabricated by selectively pattering a combination of alginate/acrylamide gel precursor solution and an epoxy based UV-curable adhesive (Emax 904 Gel-SC) with an extrusion printer. UV irradiation was used to cure the two inks into a single composite material. Spatial control of fiber distribution within the digital models allowed for the fabrication of a series of materials with a spectrum of swelling behavior and mechanical properties with physical characteristics ranging from soft and wet to…
