AI Article Synopsis

  • The scarcity of transplantable organs and issues like immune rejection and disease transmission complicate successful organ transplants.
  • Tissue engineering seeks to address these problems by creating functional 3D tissue constructs that require adequate oxygen supply for cell survival.
  • Incorporating oxygen-generating materials into engineered tissues helps ensure cells receive oxygen effectively, paving the way for potential clinical applications in organ-specific treatments.

Article Abstract

The limited availability of transplantable organs hinders the success of patient treatment through organ transplantation. In addition, there are challenges with immune rejection and the risk of disease transmission when receiving organs from other individuals. Tissue engineering aims to overcome these challenges by generating functional three-dimensional (3D) tissue constructs. When developing tissues or organs of a particular shape, structure, and size as determined by the specific needs of the therapeutic intervention, a tissue specific oxygen supply to all parts of the tissue construct is an utmost requirement. Moreover, the lack of a functional vasculature in engineered tissues decreases cell survival upon implantation in the body. Oxygen-generating materials can alleviate this challenge in engineered tissue constructs by providing oxygen in a sustained and controlled manner. Oxygen-generating materials can be incorporated into 3D scaffolds allowing the cells to receive and utilize oxygen efficiently. In this review, we present an overview of the use of oxygen-generating materials in various tissue engineering applications in an organ specific manner as well as their potential use in the clinic.

Metal-organic hybrid catalysts with highly tunable single-sites are promising for oxygen-evolution reaction (OER), but molecular-scale understanding of underlying reaction mechanisms still remain elusive on these bulk materials. Herein, we report a direct construction of heterogenized molecular complexes stabilized on carbon substrates via coordinating Fe-Ni sites with four aromatic carboxylate ligands (FeNi-L). The ligands-tuning π-π stacking interaction between aromatic carboxylate ligands and carbon supports promote the oxidative charge accumulation on Fe-Ni sites via fast electron transferring, thus the optimized FeNi-L rendering a mass activity of 6680 A g at 0.

Chronic wounds resulting from hyperglycemia and hypoxia are common complications in diabetic patients, posing significant challenges for clinical treatment. In this study, we developed a hydrogel (PVNP-SP) using [VBIM]Br, NIPAM, PEGDA, and spirulina, which exhibited strong antioxidant properties. The incorporation of [VBIM]Br endowed the hydrogel with electrical conductivity, allowing it to activate voltage-gated ion channels under an external electric field, thereby promoting cell survival and migration.

In bone, an adequate oxygen (O) supply is crucial during development, homeostasis, and healing. Oxygen-generating scaffolds (OGS) have demonstrated significant potential to enhance bone regeneration. However, the complexity of O delivery and signaling in vivo makes it challenging to tailor the design of OGS to precisely meet this biological requirement.
