Fibrin is a promising natural polymer that is widely used for diverse applications, such as hemostatic glue, carrier for drug and cell delivery, and matrix for tissue engineering. Despite the significant advances in the use of fibrin for bioengineering and biomedical applications, some of its characteristics must be improved for suitability for gen...

Biocompatible three-dimensional porous scaffolds are widely used in multiple biomedical applications. However, the fabrication of tailor-made 3D structures with controlled and combined multiscale macroscopic-microscopic, surface and inner porosities in a straightforward manner is still a current challenge. Herein, we use multimaterial fused deposit...

Size-exclusion polymer electrolytes are promising charge carriers to diminish the crossover and allowing commercially available low-cost porous membranes in redox flow batteries. Boosting the solubility in water and maximizing the number of redox sites to enhance the capacity of these polymeric systems is challenging. New highly water dispersed amp...

Fibrin hydrogels are one of the most popular scaffolds used in tissue engineering due to their excellent biological properties. Special attention should be paid to the use of human plasma-derived fibrin hydrogels as a 3D scaffold in the production of autologous skin grafts, skeletal muscle regeneration and bone tissue repair. However, mechanical we...

This article is devoted to the use of polymers in additive manufacturing (AM), also generally known as 3D printing or rapid prototyping. AM presents essential advantages in comparison to traditional fabrication methodologies since it allows the fabrication of wholly customized 3D parts and objects with astonishing levels of geometrical complexity....

In this article, the preparation of porous polymeric scaffolds of the synthetic poly (isopropylideneglycerol methacrylate) (PIPGMA) is described combining two complementary techniques. Supercritical CO2 (SCCO2), has been used as foaming agent to obtain internal porosity by varying parameters such as pressure and depressurization time. However, the...

The fabrication of porous materials for tissue engineering applications in a straightforward manner is still a current challenge. Herein, by combining the advantages of two conventional methodologies with additive manufacturing, well-defined objects with internal and external porosity were produced. First of all, multi-material fused deposition mod...
