ABSTRACT Wound healing, especially for severe injuries, require dressings that absorb exudate, prevent infection, and support healing without causing trauma upon removal. Traditional single‐layered often fail to balance moisture retention protection, hindering optimal healing. To address this, a bilayered scaffold was fabricated comprising an electrospun hydrophilic sublayer of Pullulan/Polyvinyl alcohol (PVA)/Gum arabic blend loaded with Gentamicin solvent‐casted hydrophobic top layer Polylactic acid (PLA). The designed direct wound contact ease dressing removal, while the enhance mechanical properties, loss, protect against external environment. exhibited antibacterial activity Staphylococcus aureus Escherichia coli , controlled release 93.09% ± 2.63% within 48 h, best described by zero‐order model ( R 2 = 0.9850). It demonstrated swelling index 611.85% 15.05%, indicating its excellent exudate absorbing capacity. water vapor transmission rate (WVTR) porosity were 94.20 14.50 g/m /day 70.56% 0.58%, respectively, both falling permissible range Additionally, in vitro biocompatibility assays conducted on human dermal fibroblast (HDF) cells confirmed noncytotoxicity applicability applications.

Wound-associated infections represent an arduous global healthcare challenge, especially in the "post-antibiotic" era, necessitating development of advanced antimicrobial dressing materials that simultaneously dictate use rapid yet effective disinfection, low drug resistance and side effects, potency to foster tissue healing. Nanoantimicrobial-armored nanostructured functional systems have piqued extensive interest satisfy these criteria. Herein, fusing electrospinning nanotechnology emerging photo–chemo synergistic sterilization paradigm, a smart "all-in-one" multifunctional wound-managing platform was constructed, through incorporating photochemically active nanocrystalline cuprous oxide (Cu2O) into modified polycaprolactone (mPCL) electrospun fibrous mats. The resulting were systematically characterized pertaining physiochemical analysis, photoabsorption photocurrent measurements, photocatalytic reactive oxygen species (ROS) generation. capability this nanoplatform elicit rapid, photoactivated, catalytically augmented bacterial disinfection corroborated, displaying ∼99–100% broad-spectrum antibacterial efficacies against Staphylococcus aureus Escherichia coli 25 min. Benefiting from release Cu2+, mPCL-Cu2O impairs contamination even under dark conditions. Furthermore, also exhibited favorable vitro/-ovo biocompatibility toward NIH3T3 fibroblasts, red blood cells, chick chorioallantoic membrane, alongside appreciable pro-healing capacity bridging scratch-based wounds, which could be attributed nanofiber-afforded biomimetic topography controllable liberation micronutrient Cu ions. This study provides insights design fabrication simple nanoplatforms for biomedical applications.

Traditional wound dressings have not been able to satisfy the needs of regenerative medicine biomedical area. With aim improving tissue regeneration, nanofiber-based fabricated by electrospinning (ES) processes emerged as a powerful approach. Nowadays, bioactive are mainly developed with combination natural and synthetic polymers, such polycaprolactone (PCL) chitosan (CHI). Accordingly, herein, PCL/CHI nanofibers varying PCL:CHI weight ratios (9:1, 8:2 7:3) or CHI viscosities (20, 100 600 mPa·s) using novel alternating current ES (ACES) process. Such were thoroughly characterized determining physicochemical nanomechanical properties, along wettability, absorption capacity hydrolytic plus enzymatic stability. Furthermore, nanofiber biological safety was validated in terms cytocompatibility hemocompatibility (hemolysis < 2%), addition notable antibacterial performance (bacterial reductions 99.90% for S. aureus 99.91% P. aeruginosa). Lastly, enhanced healing activity confirmed thanks their ability remarkably promote cell proliferation, which make them ideal candidates long-term applications dressings.
