 ors are freely suspended bridges with nanoscale diameters which can be dri
 ven to vibrate under resonant actuation. These nanostructures are receivin
 g an increasing amount of attention both in fundamental experiments and se
 nsing applications for their remarkable mechanical properties. However\, t
 he investigation of nanomechanical systems calls for novel transduction me
 chanisms to actuate and detect their motion\, for integrated control and t
 uning schemes as well as a fundamental understanding of the underlying dis
 sipation mechanisms to enable high mechanical quality factors.    In this 
 presentation\, I will show how the above requirements can be met using dou
 bly-clamped pre-stressed silicon nitride string resonators\, which are exp
 lored as high Q nanomechanical systems (NEMS)\, in combination with dielec
 tric gradient forces which are employed to transduce and manipulate their 
 motion. In particular\, I will demonstrate gradient-field induced strong c
 oupling and coherent control of mechanical resonator modes. Furthermore\, 
 coupling to a cavity allows for back-action induced manipulation of the me
 chanical response\, which can give rise to self-oscillation and cooling.
