Summary: Natural wound dressings extracted from Aloe vera leaves are recognized for their ability to speed up wound healing and their non-toxicity. The treated dressings remove moisture and allow gas exchange while suppressing microbial growth. Aloe vera can be applied directly to fabric or electrospun into nanoparticles. Chemical antimicrobial agents are still used due to the limited effectiveness of natural agents against high concentrations of microorganisms. However, natural fabrics treated with Aloe vera can be an alternative for chemical agents, as they prevent microbial growth and promote wound healing without activating the immune response.

Summary: This study introduces dehydrated microgel particles that rapidly swell and interconnect, forming an integrated hydrogel when exposed to fluid. These particles can significantly absorb fluid and release silver nanoparticles, effectively controlling infection. Studies validate the microgels' ability to regulate wound exudate, create a moist environment, and confirm their safety and hemostatic property. Results from full-thickness wounds in rats highlight the enhanced healing potential of these microgel particles, suggesting their potential as a new class of smart wound dressings.

Summary: Wound healing is a complex process that requires effective management. 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.
