Antibacterial electrospun nanofibers based on cyclodextrin (CD) and silver nanoparticles (Ag-NPs) were produced by solution electrospinning from aqueous and DMF solutions using different Ag contents. CD molecules acted as the reducing agent and catalyzed the formation of Ag-NPs. The nanofibers with smaller diameters were observed for the fibers generated from DMF solutions than those produced from aqueous solutions. TEM and STEM analyses revealed the Ag-NPs (~2-5 nm depending on solvent-type and Ag loading) in nanofibers, while FTIR and surface enhanced Raman scattering (SERS) analyses showed the apparent frequency shift of OH stretching band and the enhancement of Raman bands of CD molecules with the incorporation of the Ag-NPs. The polycrystalline structure of the Ag-NPs was shown by XRD and SAED analyses over {111}, {200}, {220} and {311} planes. The nanofibers showed significant inhibition against the growth of Escherichia coli and Staphylococcus aureus owing to the antibacterial activity of the Ag-NPs.

基于环糊精（CD）和银纳米颗粒（Ag-NPs）的抗菌电纺纳米纤维是通过使用不同的Ag含量从水溶液和DMF溶液中进行溶液电纺丝而制得的。CD分子充当还原剂并催化Ag-NP的形成。对于由DMF溶液产生的纤维，与从水溶液产生的纤维相比，观察到直径较小的纳米纤维。TEM和STEM分析显示纳米纤维中的Ag-NPs（〜2-5 nm取决于溶剂类型和Ag负载），而FTIR和表面增强拉曼散射（SERS）分析显示OH拉伸带的明显频移和增强Ag-NPs掺入CD分子的拉曼光谱。通过XRD和SAED对{111}，{200}，{220}和{311}平面。纳米纤维显示出显着的抑制生长的能力。大肠埃希菌和金黄色葡萄球菌归因于Ag-NPs的抗菌活性。
