An ideal wound dressing must be biocompatible, not cause allergies, and can protect the wounds from microorganisms and foreign particles. In this work, we employed the electrospinning method to fabricate a novel nanofiber membrane wound dressing from a mixture of chitosan, polyethylene oxide (PEO), and botanical collagen extracted from taro tuber (Colocasia esculenta). Scanning electron microscope (SEM) images of the resulting chitosan-PEO-botanical collagen nanofiber membrane showed braided fibers with a diameter from 50 to 292 nm. Attenuated total reflectance Fourier Transform Infrared (ATR-FTIR) spectroscopy showed that the nanofiber membrane forms hydrogen bond interactions. In the culture-based assay, the nanofiber membrane demonstrated antibacterial activity against Gram-positive Staphylococcus aureus and Gram-negative Pseudomonas aeruginosa bacteria. The results showed that the chitosan-PEO-botanical collagen nanofiber membrane has excellent potential for use as antibacterial wound dressing material. © 2026 American Institute of Physics Inc..
