Antibacterial Property of Zinc Alginate Fiber
To improve the antibacterial property of alginate fiber, zinc alginate fiber was prepared by using Zn2+ to replace Ca2+ in coagulating bath, expecting to widen the application of alginate fiber in the medical dressings. The antibacterial properties and mechanism of zinc alginate fibers were investigated. The inhibitory rate was tested using the Petri-dish count method and 3-(4, 5-Dimethylthiazol-2-yl)-2, 5diphenyltetrazolium bromide (MTT) method by the way of shake-flash. The results show that calcium alginate fiber has weaker bacteriostasis, while zinc alginate fiber has obvious inhibitive effect. The scanning electron microscopy (SEM) images show that the cell has ruptured and the surface of bacteria is scraggly after the interactions between bacteria and fibers. The excellent antibacterial property of zinc alginate fiber demonstrates its potential application in wound treatments, especially in easily-infected wound.
