Summary: Bacterial cellulose (BC) is a biopolymer studied intensively for biomedical applications. However, it lacks antimicrobial activity and has limited water retention capacity. To address these limitations, BC composites with carboxymethyl cellulose (CMC) and turmeric extract (TE) were developed using citric acid (CA) as the crosslinking agent. These composites showed high swelling degrees, adsorbing exudate from chronic wounds, and exhibited potential antibacterial properties against Escherichia coli, Staphylococcus aureus, and Candida albicans. The composites were also found to be non-toxic to fibroblast cells, making them promising candidates for wound dressing applications.

Summary: Cellulose and chitosan are promising materials for wound dressing due to their biocompatibility, biodegradability, and other characteristics. This study focuses on transforming these biopolymers into fibrous bioaerogels, which can greatly enhance their functional and structural properties. Wet spun chitosan-cellulose aerogel microfibers (CHCLAFs) were successfully produced using supercritical CO2 drying, and loaded with ibuprofen for wound dressing application. The CHCLAFs exhibited favorable characteristics, such as low density, high porosity, large specific surface area, water absorbability, antibacterial properties, cytotoxicity, and sustained drug release. These findings indicate that CHCLAFs have the potential to be used as effective wound dressing materials.

Summary: Wound healing has been a major research focus, with the aim of developing effective approaches to accelerate the healing process. Flexible and highly porous wound dressings with rapid hemostasis, good biocompatibility, and suitable porosity are gaining increasing attention. In this study, nanocomposite sponges of chitosan/polyvinyl alcohol/carbon dots were successfully fabricated and evaluated for their physicochemical properties, biocompatibility, and hemostatic efficiency. The results demonstrate that the fabricated CS/PVA/CDs nanocomposite sponges exhibit high porosity, hydrophilicity, good water absorption capacity, flexibility, and favorable biocompatibility. They also show high hemostatic efficiency in in vivo tests on rat injuries. Therefore, these nanocomposite sponges have the potential to be utilized as wound dressings.

Summary: Recently, decellularized amniotic membranes (dAM) have been modified with sodium alginate and Laponite nanoplatelets to improve their rheological behavior and mechanical durability for 3D bioprinting. The addition of Laponite significantly enhanced the shear-thinning behavior and dynamic mechanical modulus of the hydrogel, enabling the printing of free-standing constructs without compromising biological properties. However, excessive agglomeration of the nanoplatelets at high concentrations was observed, leading to nozzle clogging. Overall, the nanoengineered hydrogel showed suitable structural integrity and biocompatibility, highlighting its potential for tissue engineering applications.

Upconversion nanoparticles (UCNPs) have emerged as promising materials for wound dressing due to their unique properties. Functionalized with antibacterial agents, UCNPs have enhanced antibacterial properties and can deliver therapeutic agents to the wound site. They can also convert near-infrared light for therapy and diagnosis. However, the use of UCNPs in wound dressing faces challenges of stability, biocompatibility, efficient incorporation, scalability, and cost-effectiveness.
