A nanoscale apparatus (100) includes a nanoshell (110) extending from a substrate (102) and an epitaxial connection (120) between the substrate and an end (112) of the nanoshell adjacent to the substrate. A nanoscale sensor (200) includes surfaces (204, 206) extending relatively perpendicular to each other, a nanoshell (210) extending from one of the surfaces, and a detector (220) that monitors motion of the nanoshell relative to another of the surfaces spaced from the nanoshell by a gap (208). A method (300) of making a nanoscale apparatus includes growing (310) a nanowire on a surface; forming (320) a core-shell composite nanostructure; exposing (330) an end of the nanowire opposite to the surface with a FIB; and removing (340) the nanowire core from the exposed end, such that a nanoshell having a hollow region is attached to the surface. A material of the nanoshell (110, 210) excludes sp2-bonded carbon materials. |
