This work focuses on the synergetic effect obtained by immobilization of L. phytoextract in layered double hydroxides (LDHs) matrixes and their subsequent encapsulation into biocompatible hydrogels (HG). In this respect, the LDHs were used as hosts for the immobilization of the phytoextract by a reconstruction method, after which the LDHs were embedded into biocompatible hydrogel (HG) matrixes, based on polyethylene glycol diacrylate (PEGDA), by a radical polymerization reaction. The resulted biocompatible hydrogel composites were characterized by modern methods, while the swelling and rheology measurements revealed that the HG composites steadily improved as the content of phytoextract immobilized on LDHs (LDHs) increased. The following in vitro sustained release of the phytoextract was highlighted by measurements at pH 6.8, in which case the composite HGs with LDHs presented an improved release behavior over the LDHs, thus, underlining the synergistic effect of PEGDA network and LDH particles on the slow-release behavior. The kinetic models used in the release from composite HGs clearly indicate that the release is diffusion controlled in all the cases. The final composite HGs described here may find applications in the pharmaceutical field as devices for the controlled release of drugs.

High-performance hydrogel biomaterials hold considerable promise for advanced wound care. However, the suboptimal mechanical properties of conventional hydrogel materials limit their practical application. In this study, Hyaluronic acid sodium salt (HA), xanthan gum (XG), and N-acryloyl-glycinamide (NAGA) hydrogels with porous structures were successfully fabricated using in-situ extrusion 3D printing technology, and a functionalization strategy involving tea polyphenol (TP) immersion was proposed to enhance material properties through additional hydrogen bonding.

Wounds with extensive tissue damage are highly susceptible for microbial infections delaying the process of wound healing. Currently, biomaterials with therapeutic molecules emerged as key players in wound repairing. This work developed a novel collagen-based hydrogel loaded with allicin and silver nanoparticles.

Intervertebral disc degeneration (IDD) is a major cause of low back pain (LBP), significantly affecting on global disability and healthcare costs. Traditional treatments primarily focus on symptom management rather than addressing the underlying causes, such as the decline in nucleus pulposus (NP) cells and reduced extracellular matrix (ECM) synthesis. Cell therapy shows promise by replenishing NP cells, activating resident cells, and enhancing ECM deposition.

Radiation-induced skin injury (RSI) remains a significant clinical challenge due to persistent oxidative stress, chronic inflammation, and impaired tissue regeneration. It is demonstrated that RSI is accompanied by dysregulation of the immune microenvironment, wherein macrophages act as key regulators of all pathological cascades. Here, we developed a dual network hydrogel (Gel/SA@MXene) through dual cross-linking via UV irradiation and calcium ions to accelerate radiation-combined wound healing.

Nano-electronics based neural implants represent a rapidly advancing interdisciplinary domain at the intersection of bioelectronics, nanotechnology, and neuro-engineering. These implantable systems are engineered to restore, modulate, or augment neural functions by establishing high-fidelity, long-term interfaces with neural tissues. The design of such implants necessitates careful consideration of both materials and structural configurations to ensure biocompatibility, mechanical compliance, electrical functionality, and chronic stability.
