以硝酸银（AgNO 3）为前体，通过阳离子交换对蒙脱石（Mt）进行改性，交换Mt层间的Na+，生成Ag（+）Mt。随后使用两次浸渍和两次轧制方法进一步加强缝线（Ag（+）Mt/缝线）。当评估通过不同工艺制备的Ag+Mt/缝线的血液和组织相容性时，发现Ag+Mt/缝线表现出良好的血液和组织生物相容性。随后，当检查抗菌性能时，发现Ag（+）Mt/缝线对革兰氏阴性大肠杆菌和革兰氏阳性金黄色葡萄球菌的细菌生长抑制率为99 +/- 0.9%。(C)2014爱思唯尔有限公司版权所有。
Montmorillonite (Mt) was modified via cation-exchange using silver nitrate (AgNO3) as a precursor to exchange the Na+ in the Mt interlayer space and produce (Ag(+)Mt). The twice dipping and twice rolling method was subsequently used to further strengthen sutures (Ag(+)Mt/sutures). When the blood and tissue compatibility of the Ag+Mt/sutures prepared by different processes was assessed, the Ag+Mt/sutures were discovered to exhibit good blood and tissue biocompatibilities. Subsequently, when the antibacterial properties were examined, the Ag(+)Mt/sutures were found to inhibit bacterial growth by 99 +/- 0.9% for both Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus.
