A collisional model for AFM manipulation of rigid nanoparticles

by Enrico Gnecco , 2010
"... Abstract The trajectories of differently shaped nanoparticles manipulated by atomic force microscopy are related to the scan path of the probing tip. The direction of motion of the nanoparticles is essentially fixed by the distance b between consecutive scan lines. Welldefined formulas are obtained ..."

Toward controlling dielectrophoresis

by Dong Eui Chang, Nicolas Petit
"... Dielectrophoresis is the motion of a particle due to the interaction between a non-unifortn electric field and its induced dipole moment in the particle. With the advent of the fabrication technology at tnicro/nano-scale, dielectrophoresis is actively applied in manipulating, separating, and charact ..."
