1. A fabricated nano-fiber structure, comprising:

  • a substrate;

    a supporting stalk having a first end and a second end, wherein the second end is opposite the first end, wherein the first end is connected to the substrate, and wherein the supporting stalk has a diameter of about 50 nanometers to about 2 microns;

    a node that is disposed at the second end of the supporting stalk; and

    at least two spatular plate portions connected to the node, wherein the at least two spatular plate portions have planar geometries, wherein the at least two spatular plate portions are radially distributed about the node, wherein each of the at least two spatular plate portions has a ratio of a maximum plate thickness to a maximum plate length of at most about 1;

    20, wherein the maximum plate length is measured along a line from a boundary of the spatular plate portion to a centroid of the node, and wherein the maximum plate length is at least about 100 nanometers, and wherein the at least two spatular plate portions adhere to a contact surface using intermolecular forces when the spatular plate portions are in contact with the contact surface.
