Abstract
Solution casting a nanostructure. Preparing a template by ablating nanoholes in a substrate using single-femtosecond laser machining. Replicating the nanoholes by applying a solution of a polymer and a solvent into the template. After the solvent has substantially dissipated, removing the replica from the substrate.
Claims14
A method for fabricating a nanofiber array, comprising:
- providing a mold comprising a surface in which is formed a plurality of nanoholes [,] wherein each nanohole of the plurality is laser-ablated in the surface of the mold;
- applying a flowable polymer into the plurality of nanoholes;
- and
- extracting an array of polymer nanofibers from the mold.
