成功地生长了高柔韧性的多层羟基磷灰石纳米带，并与纳米棒进行了比较。利用原位透射电镜观察了单个HA纳米结构的纳米力学行为。压缩变形的HA纳米带在最大应变为99.2%时可以自发恢复，远远大于传统HA纳米棒的2.63%破坏应变。
Highly flexible multi-layered hydroxyapatite (HA) nanobelts were successfully grown and compared to nanorods. The nanomechanical behaviour of individual HA nanostructures was visualized using in situ TEM. Compression-induced deformation in HA nanobelts can spontaneously recover at a maximal strain of 99.2%, much larger than the 2.63% failure strain observed for traditional HA nanorods.
