Abstract

The antibacterial nanofibrous mat is crucial in biomedicine as it enhances infection control, expedites wound healing, and mitigates health hazards by decreasing antibiotic usage. A novel synergistic antibacterial and hydrophilic nanofibrous mat successfully fabricated by solution electrospinning from polyvinyl alcohol (PVA) incorporated Croton bonplandianum Baill (CBB) leaves extract. Antioxidant-enriched leaf extract of the CBB plant was integrated with PVA in varying proportions of 30% (CBB-30), 40% (CBB-40), and 50% (CBB-50) to manufacture antibacterial nanofibrous mat. The zone of inhibition (ZOI) was recorded at 16, 18, and 21 mm for CBB-30, CBB-40, and CBB-50, respectively. The wetted radius, a key parameter for moisture management properties, reached up to 20 mm for CBB-40 and CBB-50. This demonstrates the rapid absorption and quick-drying characteristics, highlighting the exceptional hydrophilicity of the nanofibrous mat. The increased dozing of CBB extract into the PVA also reduced its fiber diameter. The diameters of pure PVA, CBB-30, CBB-40, and CBB-50 were found as 396, 388, 279, and 241 nm, correspondingly. The developed nanofibrous mat, exhibiting ZOI of up to 21 mm, efficient moisture management properties, and a nanoscale fiber diameter of 241 nm, may possess significant uses in the biomedical domain.
