Abstract

A carbon-based tip for scanning probe microscopy. The tip used in microscopy to reveal chemical characteristics of a sample includes a structure of the formula: EQU X--(L--M).sub.n in which n is 1 to 100, X is a carbon-based nanotube, L is a linking group bonded at an end of the carbon-based nanotube, and M is a molecular probe bonded to the linking group.
