Electrospinning was used to load curcumin (a natural compound that has antioxidant, antiinflammatory, and anticarcinogenic biological properties) into zein nanofibers. The electrospun curcumin-loaded nanofibers showed an antibacterial property, which improved when an emulsifier, Tween 80, was combined with the hydrophobic curcumin in the zein nanofibers. The morphology of the curcumin-loaded zein nanofibers was observed using field emission scanning electron microscopy. The total immersion method was used to measure the amount of curcumin released from the zein nanofibers into phosphate buffer saline at pH 7, and the results indicated that the Tween 80 had increased the amount of curcumin released from the curcumin-loaded zein nanofibers. The antibacterial activity of the electrospun curcumin-loaded zein nanofibers against Staphylococcus aureus (S. aureus) was determined by measuring the optical density of bacterial solutions containing curcumin-loaded zein nanofibers. |
