Abstract :
This paper reports the experimental results of the micro-assembly of micron-sized NaCl crystals formed between gold microelectrodes using gold colloidal solution by capillary force and dielectrophoresis (DEP). Typical NaCl crystals formed and manipulated are ~40 mum3 cubes. From experimental results, we have determined the required DEP parameters to manipulate and crystallize NaCl cubes between or near microelectrodes with almost 100% success rate.
