We present measurements of the scaling of the dielectrophoresis force with electrode size and particle size, in order to determine the ultimate size limits for dielectrophoresis at the nanoscale. To demonstrate the feasibility of nano-manipulation we present studies on the dielectrophoretic manipulation of DNA with microfabricated electrodes using RF electric fields. We find that DNA undergoes ...

In this paper, a nano-robotic manipulation system using an atomic force microscope probe as the pushing manipulator and force and topology sensor is proposed. The task is the two-dimensional positioning of nanometer-size particles on a substrate in ambient conditions. Thus, the modeling of interaction forces and dynamics during the pushing operation is analyzed, and compared with the experiment...

Hybrid opto-electric manipulation in microfluidics/nanofluidics refers to a set of methodologies employing optical modulation of electrokinetic schemes to achieve particle or fluid manipulation at the micro- and nano-scale. Over the last decade, a set of methodologies, which differ in their modulation strategy and/or the length scale of operation, have emerged. These techniques offer new opport...

Dexterous robotic manipulation refers to the coordination of multiple fingers or manipulators grasp and manipulate a target object. In past decades, various achievements have been established in dexterous physical world. However, such ability is rarely found nano/micro manipulation, which mainly due difficulty developing actuators sensors at nano/micro-scale, as well dependence on properties ob...

Ultrasonic particle manipulation technique is a non-contact label-free method for manipulating micro- and nano-scale particles using ultrasound, which has obvious advantages over traditional optical, magnetic, electrical micro-manipulation techniques; it gained extensive attention in micro-nano recent years. This paper introduces the basic principles methods of ultrasonic techniques, provides d...

The fascinating advances in atom and molecule manipulation with the scanning tunneling microscope (STM) tip allow scientists to fabricate artificial atomic scale structures, to study local quantum phenomena, or to probe physical and chemical properties of single atoms and molecules on surfaces. Recent achievements in individual synthesis of single molecules with the STM tip further open up an e...

the theory of contact mechanics deals with stresses and deformations which arise when the surfaces of two solid bodies are brought into contact. in elastic deformation contact occurs over a finite area. a regular method for determining the dimensions of this area is hertz contact model. appearance of atomic force microscope results in introduction of contact mechanics into biology. low elastici...

During the last decade, atomic and molecular manipulations with the scanning tunneling microscope (STM) lead to fascinating advances: Probing local physical and chemical properties of atoms and molecules on surfaces together with prototypic fabrication of artificial atomic scale structures with atomic scale precision lead to the possibility of new local studies of quantum phenomena. Recent achi...
