Thermal motion of the cantilever is a fundamental limit for resolving processes with the atomic force microscope. Smaller cantilevers reduce this thermal noise in a given measurement bandwidth and allow low-noise and high-speed measurements. We have developed a series of atomic force microscopes for small cantilevers with optical lever detection and a focused spot size of 1.6 Ám. These atomic force microscopes can operate cantilevers with lengths below 5 Ám and thicknesses below 200 nm, cantilevers an order of magnitude smaller than what is currently available. We plan to apply these new microscopes to the study of proteins, Nature's nanomachines.
