Investigating the efficacy of gellan gum hydrogel films infused with Acacia stingless bee honey in wound healing.

Effective wound healing requires biocompatible and functional wound dressings. This study explores the synergistic potential of gellan gum (GG), known for its exceptional gel-forming abilities, and acacia stingless bee honey (SBH), for its potent antioxidant properties, in developing advanced wound care solutions. GG hydrogel films incorporated with varying concentrations of SBH (v/v) at 10 % (GGSBH10), 15 % (GGSBH15), and 20 % (GGSBH20) were characterized. The incorporation of SBH into the GG matrix resulted in distinctive spectral peaks of ATR-FTIR associated with SBH, particularly evident in GGSBH20. Among the formulations, GGSBH20 demonstrated an impressive water vapor transmission rate of 1149 ± 11 g m d and a swelling ratio of 169 ± 7 %. Disk diffusion revealed that E. coli was susceptible to GGSBH. Cytotoxicity assessments (MTT and scratch assays) on 3 T3-L1 cells confirmed the biocompatibility of GGSBH, which showed no cytotoxic effects up to 72 h of incubation, and improved cell viability. Notably, GGSBH20 displayed the highest wound closure rate, significantly enhancing cell migration and proliferation. Overall, our findings underscore the promising healing properties of GG hydrogel films when enriched with acacia SBH, highlighting their potential as effective and innovative wound dressing materials.
