Cantilever tales.
Building even the simplest nanomachines is a daunting challenge, but working models serve as springboards to grander designs. A classic example is the cantilever, an indispensable cog in the nanoworld that ushered in the scanning probe microscopy revolution. Today cantilevers, which resemble tiny diving boards, are the operating principle behind a host of experimental devices that could debut in the next decade.
