TECHNICAL DESCRIPTION
The invention relates to a nanoprobe and a process for producing one such nanoprobe. The nanoprobe comprises a silica fibre with an end opening having a diameter of less than 100 nm, and a metallic sheath. The total diameter of the silica part and the metallic sheath is less than 300 nm. The manufacturing process comprises the following steps : a chemical etching method, the deposition of an ultra thin metallic film on the fiber tip and the nano-aperture forming at the fiber apex.
An article untitled “Nanoprobes for near-field optical microscopy manufactured by substitute-sheath etching and hollow cathode sputtering” is added to this summary.
