Abstract
A scanning near-field optical/atomic-force microscope (SNOAM) system was applied to simultaneous topographic and fluorescence imaging of biological samples in air and liquid. The SNOAM uses a bent optical fiber simultaneously as a dynamic mode atomic-force microscopy cantilever and a scanning near-field optical microscopy probe. The SNOAM system used 458 or 488 nm from Ar ion laser multiline of excitation of green fluorescent protein (GFP), since a native GFP has been known to give a maximum at 395 nm and a broad absorption spectrum until 500 nm. Topographic and fluorescence images of recombinant E.coli were obtained simultaneously with a high spatial resolution which was apparently better than that of a conventional confocal microscope.
