Summary: An interpenetrating network (IPN) hydrogel was developed by crosslinking nanocellulose and sodium alginate through an acetic acid coagulation bath and Ca2+ chelation. The nanofibers in the hydrogel greatly extended the release time of aspirin to 60 hours, thanks to the well-structured network. Carboxyl groups played a role in the release capacity in different pH environments. This study provides a guide for the preparation of physically crosslinked IPN hydrogels with good mechanical properties and cytocompatibility for drug delivery applications.

Summary: In this study, a new photoinitiating system was developed for efficient free radical photopolymerization and cationic photopolymerization, resulting in an interpenetrating polymer network. The use of this system in zeolite-filled photopolymer materials significantly increased the depth of cure. 3D patterns with high-resolution and good water swelling property were successfully produced using direct laser write technique. Under hydrothermal stimuli, the photopolymer material with zeolite filler displayed excellent 4D printing behavior. Therefore, this photoinitiating system has potential applications in 3D/4D printing and composite material preparation.

Summary: In this study, a Copper-substituted polyoxometalate (Cu-POM) mixed matrix sequential interpenetrating polymeric network membrane was successfully fabricated via integrating engineering aspects of IPNs and in-situ electro-static attachment. The incorporation of Cu-POMs endowed the membranes with exceptional surface morphology and improved surface roughness, pore structure, and hydrophilic nature. The membranes exhibited superior antifouling characteristics and charge-carrying capacity, and maintained stable performance in terms of salt rejection, dye removal, and antibiotic removal performance over multiple operational cycles. The electrostatically tagged Cu-POM-based IPN membranes were pliable and mechanically robust, making them potential candidates for efficient water remediation.

Summary: Starch-cellulose interpenetrating network (IPN) hydrogels were prepared via sequential Diels-Alder click reaction and photopolymerization, with the addition of beta-cyclodextrin to improve performance. The sustained release behavior of drug-loaded hydrogels was studied using 5-fluorouracil as a model drug. The strategy shows potential for applications in preparing IPN hydrogels due to the controllable photopolymerization and catalyst-free Diels-Alder reaction.

Summary: This study developed a novel conductive self-healing hydrogel through an interpenetrating polymer network strategy, showing reversible self-healing in both mechanical and electrical properties. The self-healing mechanism was determined using H-1 NMR and FT-IR spectroscopy, demonstrating the cooperative effect of dynamic covalent and noncovalent interactions for its self-healing capability. The hydrogel's macroscopic and microscopic properties were examined through rheology, scanning electron microscopy, and light-emitting diode circuits, showing potential for applications in soft and conformable electronics.

Summary: In this study, IPN hydrogels with high flexibility and conductivity were prepared by modifying agar, oxidized alginate, and polyacrylamide. The presence of potassium and sodium ions in the modified agar and alginate chains endowed the hydrogels with conductive properties. These hydrogels exhibited strain-sensitive properties and can be used for detecting human motion. Furthermore, they maintained their flexibility and conductivity even after storing for six months.

Summary: Hydrogels have gained significant attention in oil-water separation due to their high hydrophilicity and low viscosity. However, their mechanical properties often limit their applications. In this study, a polyvinyl alcohol/chitosan/polyacrylamide interpenetrating polymer network hydrogel (HAPC-Gel) was created, which exhibited excellent mechanical properties. The HAPC-Gel coating filter cloth showed underwater super-oleophobicity and could effectively separate oil-water mixtures in various oil phases and complex environments. The results demonstrate the promising applications of HAPC-Gel composites in oil-water separation.

Summary: As a promising approach in translational medicine, the decellularization of discarded livers to produce bioscaffolds that support recellularization has potential in overcoming the limitations of conventional liver transplantation. In this study, the researchers investigated the use of matrix metalloproteinase (MMP) inhibition to preserve the extracellular matrix (ECM) during liver decellularization. The results demonstrated that the application of an MMP inhibitor significantly improved the preservation of ECM components and mechanical properties of the bioscaffolds, which supported cell viability and function in vitro. The study also confirmed that the MMP inhibition led to the inhibition of MMP2 and MMP9, providing a novel method to enhance ECM preservation during liver decellularization.

Summary: Human skin equivalents (HSEs) play a crucial role in tissue engineering. This study introduces a 3D-printed culture insert to apply a static radial constraint on HSEs and examines its effects on tissue characteristics. The results show that the diameter of the culture insert significantly influences tissue contraction, fibroblast and matrix organization, keratinocyte differentiation, epidermal stratification, and basement membrane formation. This study provides important insights for the design of skin tissue engineering.

Summary: This paper reviewed the primary methods for improving the overall properties of biodegradable zinc stents. It discussed the mechanical properties, degradation behavior, and biocompatibility of various improvement strategies. Alloying was found to be the most common, simple, and effective method for improving mechanical properties. Deformation processing and surface modification further improved the mechanical properties and biological activity of zinc alloys. Meanwhile, structural design could endow stents with special properties. Manufacturing zinc alloys with excellent properties and exploring their interaction mechanism with the human body are areas for future research.
