In this study, the antibacterial properties of 100% cotton terry towels, electrosprayed with gum tragacanth/ZnO nanoparticles are investigated. Various concentrations of gum tragacanth/ZnO in water and water–ethanol (70:30) are electrosprayed and evaluated by SEM. The results show that increasing the amount of ZnO (up to 200% w/w relative to gum tragacanth) lowers the mean size of the electrosprayed nanoparticles. FTIR spectroscopy proves a decrease in hydrogen bonding of tragacanth as a result of the interaction between gum tragacanth and ZnO. XRD analysis show a hexagonal wurtzite phase for ZnO nanoparticles in the tragacanth matrix. The antibacterial analyses show that the samples electrosprayed with gum tragacanth/ZnO nanoparticles are active against Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus bacteria. Briefly, in the absence of any cross-linking agent, 70% of antibacterial activity is retained after the first wash.

在这项研究中，研究了用黄aga胶/ ZnO纳米颗粒电喷涂的100％棉质毛巾布的抗菌性能。电喷雾水和水-乙醇（70:30）中不同浓度的黄/胶/ ZnO的浓度，并用SEM进行评估。结果表明，增加ZnO的量（相对于黄tr胶而言高达200％w / w）会降低电喷涂纳米粒子的平均尺寸。FTIR光谱证明，由于黄gum胶与ZnO之间的相互作用，黄aga胶的氢键降低。XRD分析显示了黄the胶基质中ZnO纳米颗粒的六方纤锌矿相。抗菌分析表明，用黄aga胶/ ZnO纳米粒子电喷雾的样品对革兰氏阴性大肠杆菌和革兰氏阳性具有活性金黄色葡萄球菌细菌。简而言之，在不存在任何交联剂的情况下，第一次洗涤后保留了70％的抗菌活性。
