Abstract
Manipulation of nanoparticles is an upcoming field with potential applications in nanofabrication, nanomanufacturing and biomedical sensors and devices. Thus far mainly mechanical methods have been used to “remove” or “deposit” nanoparticles on different surfaces with little or no control over the specificity of the particles .The use of additional control factors in manipulation of nanoparticles can serve as an attractive strategy to manipulate nanoparticles and even biomolecules in a highly specific manner. In this work we employ a new concept based on exploiting the surface charge of nanoparticles for vertical nanomanipulation method. By use of electric fields applied to a hybrid-conductive AFM cantilever (i.e. backside of cantilever is conductive but main body of cantilever and probe tip is non-conductive) we demonstrate how Au nanoparticles can be removed or lifted-off from a non-conducting surface based on their surface charge and mass. We envisage that this novel technique of using controllable electrostatic forces can be scaled up to manipulate large number of nanoparticles in parallel by use of multi-cantilever arrays or for manipulating and sorting biomolecules with specific charges and masses.
