|Title:||Direct measurement of periodic electric forces in liquids||Authors:||Rodriguez, Brian J.
|Permanent link:||http://hdl.handle.net/10197/5363||Date:||7-Jan-2008||Abstract:||The electric forces acting on an atomic force microscope tip in solution have been measured using a microelectrochemical cell formed by two periodically biased electrodes. The forces were measured as a function of lift height and bias amplitude and frequency, providing insight into electrostatic interactions in liquids. Real-space mapping of the vertical and lateral components of electrostatic forces acting on the tip from the deflection and torsion of the cantilever is demonstrated. This method enables direct probing of electrostatic and convective forces involved in electrophoretic and dielectroforetic self-assembly and electrical tweezer operation in liquid environments.||Type of material:||Journal Article||Publisher:||American Institute of Physics||Copyright (published version):||2008, American Institute of Physics||Keywords:||Liquid; Electrostatic interaction; Periodically biased electrode||DOI:||10.1063/1.2817477||Language:||en||Status of Item:||Peer reviewed|
