Abstract
The present invention is directed to devices and methods for assembling particulates through the use of non-contact electrokinetic forces applied to polymeric, organic, non-organic, and metallic micro- and nano-particulates in an aqueous solution. The present invention features an electrode comprising a conductive substrate with a layer of photosensitive polymer disposed on it with a plurality of windows etched into the layer. The plurality of windows expose certain portions of the conductive substrate. Applying electric signals to the conductive substrate (e.g. by a function generator) causes materials to attract to only the exposed portions of the conductive substrate. The materials may comprise a plurality of organic, non-organic, and metallic micro- and nano-particulates disposed in an aqueous solution.
