The nanofibers were injected in liquid form.

纳米纤维以液体的形式注入。

In a study published last month in the journal Science, researchers injected paralyzed mice with nanofibers that triggered injured spinal cord cells to regenerate.

在上个月发表在《科学》杂志上的一项研究中，研究人员给瘫痪的老鼠注射了纳米纤维，从而引发损伤的脊髓细胞再生。

The idea that nanofibers make up spider silk has been proposed before, but until now there was no evidence to suggest that nanostrands comprise the entire makeup of a silk fiber.

纳米纤维构成蜘蛛丝的想法之前已经提出，但直到现在还没有证据表明纳米线构成了丝纤维的全部组成部分。
