Abstract:
Nonlinear dynamics is substantial in nano and micro technology and physics. However, the nonlinear-
ity has not been positively accepted in the investigation of new science and technology. Recently, the
manipulation of single atoms and molecules has been experimentally achieved on surfaces with use of
scanning tunneling microscope (STM) and atomic force microscopy (AFM) in vertical and lateral pro-
cesses. The lateral processes can carry atoms and molecules parallel to the surface and the vertical
process can capture an adatom by vibratory excitation of the target-substrate bond. Recently, we pro-
posed a new mechanism of the vertical manipulation of atoms without quantum mechanics. It is shown
that, in the manipulation, the resonance has the key role in vibratory dissociation of atoms. We are
going to discuss the dynamics with consideration to the interaction between the AFM tips and surface.
Moreover, we will discuss the possibility of applications of resonance for manipulation of micro and
nano particles bonding to material surface by Van Der Waals force towards actuations. We will show an
