Research Abstract

The scanning near-field optical microscopy imaging of speciments in liquid and of cultured cells in aqueous solutions is reported. A scanning near-field optical/atomic-force microscope (SNOM-AFM) was developed, in which the scanning of an optical-fiber probe cantilever over the specimen was controlled by noncontact mode AFM (dynamic mode AFM). This imaging mode reduces damage to the probe and soft specimens. The resonant frequency of the probe cantilever decreased 20% to approximately 14 kHz and the Q factor decreased by a factor of 8 to 30 in water, compared with these values in air, which was sufficient to perform SNOM-AFM imaging in liquid.
