    "abstract": "We present the design, fabrication and experimental validation of a novel\ndevice that exploits the amplification of displacement and attenuation of\nstructural stiffness in the post-buckling deformation of slender columns to\nobtain pico-Newton force and nanometer displacement resolution even under an\noptical microscope. The extremely small size, purely mechanical sensing scheme\nand vacuum compatibility of the instrument makes it compatible with existing\nvisualization tools of nanotechnology. The instrument has a wide variety of\npotential applications ranging from electro-mechanical characterization of one\ndimensional solids to single biological cells.",
