• nanoparticles, due to their wide range of potential applications in plasmonics [1][2], magnetic memories [3], DNA detection [4], and catalysis for nanowire and nanofiber growth [5][6]. Nanoparticle arrays are typically fabricated either by chemical processes based on self-assembly or by lithography based

• ] and In the case (b): and In general, both core and cap collisions occur along each scan line and only numerical solutions are possible. However, a complete solution can be found in two important cases: The manipulation of a nanosphere of radius a (L = 0) and that of a thin nanowire of length L (a = 0

• α0 is the impact angle between tip and sphere (with the exception of the very first collision) and is given by In the case of a nanowire, the average direction of motion is well-defined and is given by the sim­ple formula [6] The wire oscillates perpendicularly to this direction: Thus, Equation 7 and

• the force F is directed along the x axis and the total force acting on the particle will be oriented as in tapping mode only if the static friction f can balance the component of F along the island profile.
