a Scanning ion microscopy image of the FIB-fabricated diamond NV tip. b Photoluminescence image of the diamond NV tip. c Schematic of photoluminescence measurement to confirm the NV centers in the diamond tip. The photoluminescence was collected by an avalanche photodiode through a confocal microscope after the irradiation of a 532 nm cw laser at 135 µW. d Top view optical image of the diamond NV probe attached to the cantilever. e Side view of the diamond NV probe attached to the cantilever. f Optical image of the self-sensing cantilever with a diamond NV probe.
