Summary: We synthesized nanocomposite (XG-AVE-Ag/MgO NCs) consisting of bimetallic Ag/MgO NPs, Aloe vera extract (AVE), and biopolymer (xanthan gum (XG)) to achieve synergistic antibacterial and wound healing effects. XRD analysis confirmed the encapsulation of XG in XG-AVE-Ag/MgO NCs. The NCs exhibited high antibacterial activity against B. cereus and E. coli, with larger inhibition zones and lower MIC values. In vitro cytotoxicity and hemolysis assays demonstrated the non-toxic nature of XG-AVE-Ag/MgO NCs. Furthermore, XG-AVE-Ag/MgO NCs significantly enhanced wound closure compared to the control group. These findings highlight the promising potential of XG-AVE-Ag/MgO NCs as a non-toxic, antibacterial, and wound-healing agent, warranting further in vivo studies.

Summary: Rapid and complete wound healing is important in pathological conditions such as Type 2 Diabetes mellitus. Wound dressings, particularly biocompatible hydrogels, play a crucial role in diabetic wound healing by retaining moisture and preventing bacterial infection. In recent years, functionalized hydrogels with natural bioactive compounds and biomacromolecules have shown promising outcomes in promoting healing and exhibiting antibacterial activity. This review discusses the discoveries and advancements in using naturally occurring compounds and biopolymers for wound healing, as well as emerging approaches and devices for effective wound care in diabetic patients.

Summary: Nanofibers containing silk fibroin, chondroitin sulfate, and silver sulfadiazine were prepared using electrospinning technique. The addition of poly (ethylene oxide) improved the electrospinnability. The nanofibers had a diameter between 262 and 328 nm before PEO removal and between 242 and 345 nm after PEO removal. CS and SSD remained in the nanofibers, and CS significantly influenced the remaining SSD content. The nanofibers were non-toxic to Vero cells and had antibacterial activity depending on the concentration of CS.

Summary: Pathogenic bacterial infection is a common wound complication that poses a major challenge in wound management worldwide. Collagen-based nanocomposite dressings with broad-spectrum antibacterial activity have been developed to promote healing of infected full-thickness wounds. These dressings demonstrate long-lasting and effective antimicrobial activity, as well as promoting blood vessel generation and collagen deposition in the wound site. Overall, the functionalized collagen-based nanocomposite dressings have great potential in the clinical treatment of bacteria-associated wound infections.

Summary: In this study, Schiff-base controlled release fertilizer (CRF) hydrogels composed of dialdehyde xanthan gum (DAXG) and gelatin were fabricated through a simple in situ crosslinking reaction. Increasing the content of DAXG in the hydrogels resulted in a compact network structure. Phytotoxic assay indicated that the hydrogels were non-toxic to different plants. The hydrogels exhibited good water-retention behavior in soil and remained reusable even after 5 cycles. The release of urea from the hydrogels followed a controlled release profile influenced by macromolecular relaxation. Growth assays on Abelmoschus esculentus (Okra) plant provided an intuitive evaluation on the performance of the CRF hydrogel in terms of growth and water-holding capacity. This study demonstrated a facile method for preparing CRF hydrogels to improve urea utilization and soil moisture retention.

Summary: Currently, commercial glutaraldehyde (GA)-crosslinked bioprosthetic valve leaflets (BVLs) face problems such as thromboembolic complications, calcification, and limited durability. This study introduces a collaborative strategy using double crosslinking agents to enhance the mechanical and structural stability, hemocompatibility, and anti-calcification properties of BVLs. The strategy involves crosslinking decellularized porcine pericardium (D-PP) with dialdehyde xanthan gum (AXG) and curcumin to obtain AXG + Cur-PP, which showed improved anti-thrombotic properties and endothelialization potential, milder immune responses, and excellent anti-calcification properties compared to GA-crosslinked PP.

Summary: In this study, novel hydrogels based on collagen and xanthan gum were investigated. The hydrogels showed characteristics of accelerated gelation, super water absorption, and high inhibition capacity against pathogenic bacteria. Increasing the content of xanthan gum in the hydrogel improved storage module and resistance to degradation while allowing controlled release of drugs. The hydrogels also exhibited excellent hemocompatibility, enhanced cell proliferation, and the ability to modulate inflammation and promote wound healing.
