A method for fabricating assembled structures. The method includes
providing a tip structure, which has a first end, a second end, and a
length defined between the first end and the second end. The second end
is a free end. The method includes attaching a nano-sized structure along
a portion of the length of the tip structure to extend a total length of
the tip structure to include the length of the tip structure and a first
length associated with the nano-sized structure. The method includes
shortening the nano-sized structure from the first length to a second
length. The method also includes pushing the nano-sized structure in a
direction parallel to the second length to reduce the second length to a
third length of the nano-sized structure along the direction parallel to
the second length to cause the nano-sized structure to move along a
portion of the length of the tip structure.
