A nanomechanical testing set-up is developed by integrating an atomic force microscope (AFM) for force measurements with a scanning electron microscope (SEM) to provide imaging capabilities. Electrospun nanofibers of polyvinyl alcohol (PVA), nylon-6 and biological mineralized collagen fibrils (MCFs) from antler bone were manipulated and tensile-tested using the AFM-SEM set-up. The complete stress-strain behavior to failure of individual nanofibers was recorded and a diversity of mechanical properties observed, highlighting how this technique is able to elucidate mechanical behavior due to structural composition at nanometer length scales.
一种由原子力显微镜（AFM）进行力测量与扫描电子显微镜（SEM）提供成像功能集成的纳米力学测试装置被开发出来。利用该装置对聚乙烯醇（PVA）、尼龙-6 和鹿角生物矿化胶原原纤维（MCFs）的静电纺纳米纤维进行操作和拉伸测试。记录了单个纳米纤维完整的失效应力-应变行为，并观察到了多种机械性能，这突出表明了该技术能够阐明由于纳米尺度结构组成而导致的机械行为。
