1. A method for fabricating a single micro- and/or nano-scale fiber or plurality of micro- and/or nano-scale fibers with a flat tip comprising the steps of:
providing a negative mold with a plurality of angled holes patterned in photoresist material disposed on a silicon substrate, wherein an outer surface of the silicon substrate is exposed between adjacent angled holes of the plurality of angled holes; pouring a liquid polymer into the negative mold to fill the plurality of angled holes, wherein the liquid polymer contacts the outer surface of the silicon substrate; curing the liquid polymer in the negative mold while in contact with the outer surface of the silicon substrate; and delaminating the cured polymer from the negative mold to form the micro- and/or nano-scale fiber with the flat tip.
