Abstract :
We report a new scanning probe based method to achieve a controllable direct "writing" of metallic nanostructures. By scanning a gold-coated scanning probe tip on a single crystal silicon surface in ambient environment, nano-sized gold dots and wires were directly formed as a result of direct gold material transfer from scanning probe tip onto silicon surface. Such gold nanostructures could be readily interfaced with silicon microelectronics for the development of integrated nanobiosensor systems.
