演講摘要:
Scanning near field optical microscopy (SNOM) is a scanning probe technique that combines optics with atomic force microscopy (AFM) to achieve sub-diffraction limit optical resolution. We design and build a horizontal-type aperture based SNOM setup (a-SNOM) with superior mechanical stability toward high resolution and non-destructive topographic and optical imaging. We adopt the torsional resonance (TR) mode for the AFM operation to achieve a better force sensitivity and a higher spatial resolution even with the blunt a-SNOM tip. In this talk, we will first present simultaneous SNOM fluorescence and topographic imaging of transition metal dichalcogenides (TMD) and self-assembled P3HT nanowires with a lateral optical resolution of 60~80 nm. Finally, SNOM imaging of fluorescent dye-labeled lipid domains is successfully achieved without sample damage by our horizontal-type a-SNOM system.
