Hybrid 3D Printing of Advanced Hydrogel-Based Wound Dressings with Tailorable Properties

Injectable 3D hydrogel scaffold with tailorable porosity post-implantation.

Since rates of tissue growth vary significantly between tissue types, and also between individuals due to differences in age, dietary intake, and lifestyle-related factors, engineering a scaffold system that is appropriate for personalized tissue engineering remains a significant challenge. In this study, a gelatin-hydroxyphenylpropionic acid/carboxylmethylcellulose-tyramine (Gtn-HPA/CMC-Tyr) p...

Printable Biodegradable Hydrogel with Self-Crosslinking Agents for Wound Dressings

The printed Biomaterial Laboratory at UTEP does research a printable hydrogel which can have appropriate properties for tissue engineering of the skin. Skin is the largest organ in our body which protects us from the environment and pathogens. Skin can be affected by burns and also by diabetic foot ulcers. The current tissue engineered skin substitutes for treatment of diabetic foot ulcers have...

A review on polymeric hydrogel membranes for wound dressing applications: PVA-based hydrogel dressings

This review presents the past and current efforts with a brief description on the featured properties of hydrogel membranes fabricated from biopolymers and synthetic ones for wound dressing applications. Many endeavors have been exerted during past ten years for developing new artificial polymeric membranes, which fulfill the demanded conditions for the treatment of skin wounds. This review mai...

Multifunctional 3D printing of heterogeneous hydrogel structures

Multimaterial additive manufacturing or three-dimensional (3D) printing of hydrogel structures provides the opportunity to engineer geometrically dependent functionalities. However, current fabrication methods are mostly limited to one type of material or only provide one type of functionality. In this paper, we report a novel method of multimaterial deposition of hydrogel structures based on a...
